- Heart rate & Oximetry sensors have been around for a while. Can you rely on them to provide critical data?
I took a look at two different types of cheap sensors with some mixed results.

The RCWL 0530 solution is so spot on. Thank you.
Thank You! Probably the most valid description and tutorial about these pulse oximeter sensor on youtube.
For sure
Small correction at 1:35, It's PPG not ECG. Great video btw!
Hey Mike, thanks for the introduction. I'm trying to use a MAX30100 using online codes I have found, but upon examining the code, I'm having difficulty finding the pin assignments (possibly in some library) as well as certain variables in the code such as (beat) or (SpO2). Is there any resource or tutorial I can read to get a better understanding. I'm trying this with Uno, but eventually want to try it with the Lilypad. Also, if you could post your source code to study, that would be great !
Hi, I just ordered the max30100, so for it to work properly, I have to apply 3.3V to INT pin and 5V to VIN pin? I don't want to mess up with the board and also I don't have the other resistors right now. Nice video!
Great video! One question, using the max30100 can i plug the pull-up resistors to 5V or it could burn out the sensor
Hi! A very useful video. Thanks a lot! Can Max30100 measure HRV?
hi, is the Max30100 sensor have temperature reading also??? or just measure pulse and oxigen level in blood??one more is this device suitable to use at wrist to measure???
Ha! I work for AMS who makes the TLS2561. That device is too slow for heart rate. Minimum integration time is 2.7ms.
I would recommend you take a look at the AMS. AS7024. It has heart rate, pulse ox and ECG capabilities.
+David Dennis
Yup I used the TLS2561 just as a proof of concept. That you can use anything that detects light. It did actually work well enough to pick up my pulse.
So good job on the chip!
Did they stop making AS7024? I was looking to get one to try it but could not find a seller
Thanks Mick
Hi! Where can I get the sample code? Or could you pass it to me please? It would be super helpful
Interesting. I mentioned the other day that I thought I'd seen you in traffic ...
Well, I was taking Mum to see GP. GP detected irregular heartbeat. Off to hospital then for surgery.
I noticed there in ICU that SpO2 reading for heartrate were consistently higher than those from ECG (though the difference varied)
Perhaps this is a widespread issue?
Nonetheless it didn't seem to phase the staff. I guess heartrate is just a small part of the story in that context
+David McDonald
Yup. My sister is an ER nurse and so I hammered her with questions before I made that video.
As I mentioned in my video; they need to assess a lot of variables and SpO2 is only a small facet. It provides a general guide of a patient's state, but can't be relied upon as the single source.
The Fibrosis issue I mentioned is a real concern for hospital staff; as the immediate response to "lack of oxygen in the blood stream" is "give more oxygen", but it's not always the correct thing.
hello, do you have code of 30100 can be used with teensy 3.2 and/or Sparfunk Sam21?? I need purchased it
Excuse me where did you put the 10 k resistor, i don't speak english really good so i didn't get it, would you tell me wich pins did use to put the 10k resistor, and if it is 2 or just 1
Well done on the affiliate.
My first HRM would attach to the ear lobe - do these work there too?
+Aaron DC mediA
Thanks, getting there.
Ear lobe? Absolutely! Although it'd move around a bit and cause misreadings.
You could stick it to your head as well. Any body part will do.
MicMake, how do u make your app about MAX30100.? please teach me . Thanks u so much, Hope u replied me soon
Nice video. I have a teensy in my parts box.... must get around to using it, so far the Uno clones are worked for me but I'm sure I must be missing out.
+NivagSwerdna
The teenies are great for audio apps. Paul has put in a lot of work on those libraries.
Thanks alot but does the drawn signal is ppg signal ????
Quite nice mate, as always! I was just thinking that your work is a great contribution to humanity. Let me explain. If there are (be generous) 1,000,000 Makers on the planet, and 10% of them use the better products, as you suggest in this video, and reject the lesser ones, then say that 100,000 new Makers come in each year (and the same go out), the new Makers must learn so they will Ggl to your videos (no I've not gone round the twist I'm a retired electrical engineer I think like this). So over say 10 years you could be saving millions of dollars and person-hours of money and time. Nicely done mate!
Thanks mate! That's the intent of my channel. Save people time with what works and what doesn't.
Does MAX30100 measures body temperature as well ?
many thanks - which sensor would you reccomend to get some propper results - for EKG ecg
I haven't looked since I made this video. I know that sensors have improved a fair amount and you can get some ultra-low current versions now.
Kindly please can you help me. Why it is failed to read sensor. I am using an Arduino Uno board with the same library. thanks.
If i am using MAX30102 i still need to remove those rezistors ? Because i did and don't work. Is not even powered..
Hi I had wired all connection as per the schematics, after uploading the code & clicking on the serial monitor, after initializing I am getting a corrupted reading like ??????Ii????????, why is this so? is thee something wrong with sensor or coding?
Waiting on your Asus SBC review. I hope you get one.
+EyesofNova
Mate, I'm sure I have one on order!
I'm sure you do! Can't wait to see your thoughts.
Hi Mick, Thanks for you video, I am trying to use the MAX30100 sensor with the library MAX30100 but the beat doesn´t belong to the correct measure, I am having measures between 30-35 bpm y 93%-95% SpO2, Do you know what could be the problem? Please help me!!
+kriss miñano
I'll reply to your email.
Can you please post the code you have used!
Hi Mick, I'm Steven. Thanks for you video, I am trying to use the MAX30100 sensor with the library oxullo/Arduino-MAX30100 but the Spo2 doesn´t belong to the correct measure, I am having measures just 94% SpO2, Do you know what could be the problem? Please help me!!
A reading of 94% is about right for SpO2. You will find it really doesn't change much at all. Expect readings from 92% to 96% anything out of that range; I'd go and see a Doctor... or check your code. :-D
Great video!!!
Thanks mate.
Is it possible to read the pulse from the intern elbow with this sensors? Have you tried it?
+Joaquin Martinez
You can read a pulse from many places, but skin that has bones near the surface you may or may not experience problems. It all depends on whether there’s a blood vessel nearby.
Blood oxygen saturation measurement isn't really pointless in non-medical settings. For example, the clip-on finger sensors are becoming pretty common among pilots of non-pressurized aircraft to help detect what would otherwise be the insidious onset of hypoxia. Truly a life-saving technology, even in the hands of the untrained (medically untrained, that is).
+FlyingShotsman
Thanks for that! That's really interesting to know that. How often do they check?
Oh, it's up to the individual, but I would try to do it at least every 20-30 minutes above 10,000 ft. More often and at lower altitude at night.
I gather you are a pilot? Nice. What are you flying?
Yes, B-737. It's a pretty swell gig, though as you can tell from my posting times, the hours are a bit variable.
Cool. Yup, there's always a downside to every job, but flying... man... It takes a certain type of person to do that job and do it well.
My auto locking BPM light strobe should interface directly to one outputting the analogue style waveform.
+TheProCactus
Yup should do.
I have the code on GitHub if anyone interested.
Yeah, fire it up!
I probably should warn anyone trying to use this.
It is my very first program in C (Arduino), Its rough.
It requires a 16x2 LCD and a mic module of some kind.
github.com/ProCactus/makeitANDhackit
Shit, I think its the wrong code. OMFG.
Ill have to check it, Dont waist your time on it yet.
Does it need code?
What's with the bulldogs breadboards? Are you a tigers fan or what?
+Darryn Jones
Ha ha. They're my son's. He's a bulldogs fan by default. Since he works at Jaycar.
Good aftertoon, Thanks for your video, I am trying to use the MAX30100 sensor with the OXULLO library but the beat doesn´t belong to the correct measure, I am having measures between 30-35 bpm, Do you know what could be the problem? Could you pass me your arduino code for other testings please? Thank you very much in advance, regrets.
I have the same problem only readings around 30 bpm...
Moritz Waldemeyer
This is really odd. You're now the 4th person to have this issue. Seems I need to do some investigating on this.
That would be amazing! I've spent hours and hours trying to find a solution. I found a few more mentions of the problem on the internet, but not even a hint of a solution...
thanks for video. i used max30100 to finger.but i want to wrist use this. how should i do it? please teaching me.
+Ashtarte Nylia
You should be able to stick the sensor almost anywhere and have it pick up your heart rate. The wrist will be no problem.
MickMake Thanks for your comment
hello need help for project on spo2 measurement using 8085 microprocessor.. can i use max 30100
+afaq anzar
Sure! The 30100 can handle 5v logic.
MickMake
sir this max 30100 gives I2c value..
and 8085 is uart
so sir how will i do it??
and can this be shipped to india?
also provide me your email id please
thank you
You would have to bit bash the I2C. Easy enough to do on an 8085.
My email address is in the "About" section
MickMake
sir
please tell me how bit bash the i2c
in detail
Nice.
+MDF RESCUER
Thanks!
Alguien pudo hacer funcionar el MAX 30100 con PSOC 4 BLE O PSOC 5LP ? AGRADECERIA UNA AYUDA !
We are waiting you. We need to codes. Plz this is our graduate project. 🙏🙏🙏
We are waiting you sir😘😘😘💚💜💙💜💚💜💞💞💞💞💟
The cheap modules aren't cheap when compared to modern wearables coming from china which come for the same price as of the "cheap" modules but with much more functionalities. I think these modules can get much more cheaper with time.
+Akarsh Agarwal
Yup that's true. I have a video brewing on just that topic. IE when is it cheaper to just buy a product off the shelf?
RGB LED recessed downlights. I don't know how to make them that cheap.
I recommend ordering a miband 1s or miband 2 from Xiaomi as one of the products to test. I can't justify ordering a fitbit due to the price so these worked pretty well for me.
yeah the miband1s was the product which I kept in mind while writing my comment.
Hellow, it's possible pass the arduino code to me?
+Micojim Darckbs
Absolutely, but I'm on holidays at the moment with no access to all my stuff.
Can you pass code MAX30100
How can I get the code for MAX30100 arduino program
Think I may need to stop watching your videos haha :-P. Its costing me too much money.
First thing I did after watching this was go and purchase a MAX30100.
Same thing happened with your Orange PI Zero video, and the NanoPi video, and the C.H.I.P. video.
But not the Pine64 :-P
Thanks anyway for another enjoyable video.
+vk2amv
Ha ha. So what have you made with your Pis and CHIPs? I might have to publish some tutorials. Let me know if you have any ideas. I have a bucket load, but you might have one I don't have.
Actually I more like collecting different Pi boards for general Linux use and simply because I am a bit of a collector than anything else.
I have several Raspberry Pi's from 1 to 3 (Including a Pi1 B from the original 10,000 run)
Couple of Banana Pi's (M1 from before it was called M1, and a M2)
Some Orange Pi's on the way. (A Zero you reviewed and a One Dave Jones reviewed)
Some NanoPi's on the way. (Neo, Neo-Air, M2)
And two C.H.I.P.'s on order.
Also a few other Allwinner and Rockchip based misc devices, eg Mele A2000 and others
To be honest I have not ever used a Pi type device for interfacing with sensor's, controllers, or anything like that.
I mainly use them as small headless Linux PC's for other jobs, and only one of all the Pi's I own are plugged into a monitor. (As a RetroPie emulator)
Just for example I have two Pi's running at the moment (And they have been there for a few years now) sitting in a hut up on a hill on the edge of town monitoring a 21 Kilometer 5.8Ghz Point to Point WiFi (WhyFy) link for stability and other statistics.
They run the smallest linux distro I can find (Minibian so far) and all they do is run OpenVPN to connect back to me, run SmokePing, and a few other utils to report link health and errors.
I also use them for small low power server usage at home for a few different things as well.
If I ever want to make something to interface with a sensor and/or controller I normally use something Arduino based, or ESP8266 based, or Micromite (A PIC32 with BASIC firmware flashed) based.
I have yet to do anything that has required the power of a Pi type device.
Though one day I will likely reach that point, it just has not happened yet.
Anyway sorry for such a long winded reply.
Keep up the good work and I will keep watching.
+vk2amv
Nice work! I'm pretty much doing the same with sensor work. I rely on small MCUs and work with serial or wireless back to an SBC.
I'm preferring wireless more and more. I'm actually thinking of doing a battery uptime comparison video comparing several wireless protocols.
