- FS100A and XY-MK-5V are super cheap and super simple 433MHz modules. Some people report they work well, some that link is lost even at a range of few centimeters. I've decided to test that, and do a proper range test in open space.
With proper antennas, those little 433MHz modules can have a decent range. Who would expect that...

I tried these for use outdoors. Range in the city with coiled antennas was about 30m but gradually decreased. I discovered the receiver is very sensitive to temperature, with the range only 1m at -15C. Useless for my application. I’m looking for a substitute.
Nice presentation. I perchased several variants of these inexpensive ASK modules. Its fun testing them. Your test rig is cool. I will dedicate the Nano's when I get better at it. Thanks for the Show.
This is one of the most useful videos I have ever watched, great work👍👍
Glad you think so!
Great job. You have done a job that allows others to believe that these simple components work not bad at all and can be used.
Thank you, it helps me a lot.
Great job sir ...m also impresse with your knowledge .wow
These modules are also excellent to listen to doorbells (sender) or to activate doorbells (listener). ;-) With these you can combine different models or brands and use only one doorbell knob (sender) to trigger all doorbells by sending all the codes required. Using RF switches (listener), it is possible to activate or deactivate lights or other equipment remotely from your arduino.
Any video explaining how these 433 mhz transmitter and receiver circuit works , what is the function of every components used in the schematic , how the signals are transmitted from transmitter to receiver to control the e.g. motors of the RC toy
Nice video, thanks for sharing :)
Thanks for watching!
you can use a loop antenna to deal with interference, they have a null in the vertical axis
Nice!!!
that fs100A like a dream but if you change also crystal different frequencies also = anyway good job bro
Sir can you say about the antennayou used is it available to buy
Very helpful for me tnx
My pleasure
Thanks you just saved me from spending more money on new transmiter, I just had to get a bigger antena for it HAHHAH
Hey I know this is kind of an old video but I have a questionand sorry if it seems stupid but I know nothing about this. Im big into rockets and I was wondering could you hook up extra wires coming off the receiver to a fuse to iqnite the thermite in the rocket engine with current?
How much voltage did you connect to the transmitter?
hi good test but not enough = tx antenna next to little capasitor move it and solder directly and same length of anttena directly to opposite to ground (-) make a dipol antenna = see the resolt.= 800m open area without loss
Hey, I have a question on the antenna you built. is a monopole, but can you increase range converting it to a dipole (adding the gnd) ? is it possible?
yes, but I would not expect a huge range gain from that
Car Tyre Pressure Monitoring Systems (TPMS) work on 433MHz, so placing your TX/RX modules on the car and saying "this should be free of interferance" is quite ironic!
Another video I've watched says your attennas should be 173mm from solder point to end to work best at 433MHz.
What kind of antenna did you use?
Hello , I have a question .
In my project I would need to acquire (very relatively ) the distance between the transmitter and the receiver , through a calculation between the time of sending the message and the time of receiving . With 2 arduino , both with one transmitter and one receiver each .
the first send a message and marks time , the second receives it and sends it right back , the first receives it and marks time again . I wanted to know if you have an idea (more or less) , how long the travel time ( in ms) could be , if the transmitter and receiver were 5 meters or 10 .
ranging in those short distances is not something that can be easily done at home. You can take a look at SX1280 from Semtech which has ranging capabilities but I'm not sure if it will be precise enough for your application
the resolution of time isn't enough to do time of flight calculations
but i have an idea to deal with that, you can send the same packet like a ping pongg between 2 arduinos that have both emitter and receivers
you should send the packet with a timestamp 1000 times for example then you can have enought resolution to estimate time of flight
but you should calibrate each time for distance 0
i could transmit data and include in arduino a giga ethernet port ?
Pls check all this type of rf ,rx-tx
I have a strange problem sir😂, i built the two antennas like yours antennas but nothing works. Then i accidentally touched with my hand the transimmer antenna and it immediately started to transmit, what can be the reason of this problem?
Same problem
Hello friend, I downloaded a software developed by you (e45config), but I have a problem opening the port and reading the configuration of the module, I'm working on debian.
the error in console is
Write cmd = c3, len3, expect 4
Read [00 00 00 00 ]
Unexpected
I appreciate your help
How to build those radio transmitter and reciever to measure distance? what components are needed to build those?
those modules have no ranging capabilities
@@PSAfterHours I am new with these things but currently we are making a project for our school, I saw in your video you were able to measure between two points, may I ask what components did you use to be able to measure between two points and what codes did you use? Please if you could take your time to explain properly it would very helpful for us since I'm not knowledgeable at these kind of things. Thank you
@@RalphjanTocong-zd7ho that was just GPS tracking mobile app.... No module required
What is tha maximum range ??
Can it transmit 4 channel signal properly between 3rd to ground floor.
You will not do it with those modules. They are 1 channel only and work through one roof only in the best of cases. So no, don't use them
Hi. I am experimenting with these modules, but they work wthin a few centimeters only. Even when I add an antenna to one or both of them it extends the range to 1 meter only.
I have 4 pair of them, so I tried to combine them without any success. Also tried to tune it, did not help either. Do you have any idea, what could be wrong?
Try these :
1. Use half wave antenna 34.6 cm wire for the transmitter
2. Power transmitter with 12V, receiver with 5V + decoupling capacitor on power rail
3. Make sure both transmitter and receiver antenna are on the same plane (both vertical for horizontal range or both horizontal for vertical range)
4. Transmit data at a very slower rate like 128 bit per seconds
If they are still not working well, try adjusting the inductor with a screw driver on the receiver module to match the frequency better
Or buy RXB-6 modules which are apparently better than FS1000A ones
Why reciver contineously working without getting any signals and please tell me how it works with far mic and arduino
It just picks the RF noise. It's also not for audio transmission. It's digital only and at very low speeds
What voltage was on the transmitter module?
8V
@@PSAfterHours Thanks for the info!
What bit rate did you use?
1000 bps
oww I forgot you can use 12v to power it and signals can go to Mars ::)
Hi friend, I hace a module with 5vcc if I feed it with 12 vcc, do You think I can extend it's Range? Thank You!!!
i am facing a challenge of overlapping frequencies when using with more than 1 module at a time
This is how they work, there is no simple workaround. When 2 are transmitting, they will jam each other
Hi . I want to make a project with 2 Arduino , each Arduino have its Transmitter and Receiver .
A very simple test I want to make , is a simple continuosly handshake between them.
The first Arduino send a message with his transmitter , the second Arduino received it with his receiver and send immediately a message with his transmitter which is receive by the receiver of the first Arduino .
In this way there isn't a overlapping frequencies because each transmitter and receiver wait before send or listen for a message.
This module is great..
This module is total garbage 🤣
@@PSAfterHours why would you say that 😁.
@@PSAfterHours Can you pls present a better moudle ? i need that
Put it on a plane and test it.
Use Google earth to measure distance
polska
ähhhhhh
Ammm ammm ammmmmmm
