Have you tried the internal temperature sensor code ???
In DS3231 RTC module
Yeah, I've tried the internal temperature sensor code; gives the same value as 53.33°C always.
in the convertion to celcius , if we solve 53.3333 to the temprature sens read , it comes out 63.994 , like almost 64 , witch is halve of 128 .maybe it is defaulted to that value .
I have uploaded a similar sketch to two dev kit esp32 modules and both give the correct (well they both measure but not accurate) temperature. One module if quite old and the other is a new Chinese ebay module.
Excellent tutorial. - Keep up the good work. Thanks for the share.
You are videos are really helpful as there is a very few videos available on TH-cam about ESP 32
Fantastic tutorial
Cool bro, awesome tutorial n solutions.. keep it up.. N a Very Happy Diwali to you n all our techie's..
Same to you man
/Nice Video!! I was looking for something like... Explaning function by fuction
Nice video. I've also observed "Temperature in deg Celcius: 53.33 C
" with my ESP32 Dev board.
Ohh
Thanks for the info
Sir by using two libraries you can go for analogWrite in esp32 as well. The two libraries are #include and #include
Thanks it works for me
50$ is courier charges for INDIA , PCB charges is 4$ (dual layer) total = 54$ which is 4,269.64 Indian Rupee , which is very costly for 10 PCB !!
cool bro
LED not glowing fully in ur code because of ESP32 accept resolution upto 1024 (it's 255 in Arduino). PWM on ESP32 is different from Arduino. Even Servo library of Arduino won't work on ESP32 directly.
Hey techisms, which software you use for video editing your videos are getting professional day by day.
Recently I purchased MacBook Pro
And now a days I’m using Final Cut Pro x for editing
My temperature is also stuck at 53.33°C. Is there any solution?
👌😎
👍👏
Hi.. Bro you make an WiFi camera using esp32
temprature_sens_read() returns 128 = 53.333 (sensor not present)
Obsolete since 07/2018 unfortunatly
i am also getting the same values
53.33 with my wemos with built in OLED.
Hi buddy, if possibly connect the multiple esp with one esp like single master and multi slave ? For Home automation
Yes it’s possible
@@techiesms Thanks a lot buddy first time i am getting reply from a youtuber, Could you provide your tutorial or link if you have, Thanks in advance.
I don’t have one
But in future I’ll surely make
@@techiesms thanks buddy
Same output Temperature in deg Celcius: 53.33 C
I've tried the code ,It's the same result of your , 53.3c
Yep, 53.33C is what I get. Anyone have an answer yet to why this is?
yes
its is 53.33 celcius
temperature fluctuated between 41 to 43 C
also 53.33
wow! interesting , is all code of esp8266 is compatible with esp32 or not
Not necessary
Some of the code required modification
@@techiesms ok thanks, plz check u r fb page msg
Same output Temperature in deg Celcius: 53.33 C
:\
i am also getting 53.33 Celsius only
Why would Espressif make a sensor that outputs Fahrenheit? They are not an American company. Crazy.
Maybe the function "temperature_sen_read()" was written by an American.
Possible
53.33.…… A FEW MOMENTS LATER ………. 53.33
my ubidots account want money to active my account you also paid for your account
1:00 The Esp32 has code for the temperature sensor in the arduino IDE.
1:23 Yes there is no AnalogWrite, but you can impliment it yourself. It is just around 3 lines of code.
2:40 Most C++ supports (most) C backward compatibility. You can use C code in C++. We use extern C to mostly import from ,c files
7:00 i think the temperature is the temperature of the microcontroller and not of the room. (Do not quote me on this, i couldn't find the source myself in the datasheet)
Jeez man, i think you yourself need to learn a bit more about the board and the C++ prgramming language first.
Where is it ?
@@techiesms Couldn't find. I would have sworn that there was an example in the example section. By the way, i have edited my post.
Thanks for sharing your experience
But I haven’t shared any wrong information, have I?
First you told temperature sensor example was available but right now it’s not available.so this was correct information from my side
Secondly you told we can implement the same function as of analogwrite in a esp32 code. Well I have also taught that method to make your own PWM signals using other functions. Again correct information
Then you Said most of the c code works in c++. Correct so you just gave a more detail introduction about extern c which is the only thing I appreciate from your comment. But as I
Said in the video I too was not knowing details about extern c. Whatever i have explained that particular thing I learned from other video whose link is also attached in the description
At last you said about the temperature sensor. First of all if you are not confident about your answer then why to mention it.
You said that it shows the temperature of processor but it’s not mentioned anywhere. While I have also seen one video In which he is getting variable temperature value by exposing esp32 under bulb light so what about that???
I think you should watch the video twice and then comment below as whatever I have said in the video is correct based upon the current scenario
@@techiesms
To my first point: I tought the example was availble. Sorry.
To my second point: you said the analogWrite wasn't available. I mean, it is a function and anyone can write functions.
To my third point: You are welcome
To my fourth point, i said, i thought is was the microprocessor temperature. Surely the temperature will increase near a hot source. Read cdn.sparkfun.com/datasheets/IoT/esp32_datasheet_en.pdf Paragraph 4.6 (I recommand you read the whole datasheet, if you are interessted in the board). The temperature sensor is not particalar accurate (because of the offset) and some datasheets do not even mention this feature.
How can you say eveything is correct, when you notice that for example the ''extern c' stuff that you said wasn't accurate?
@@techiesms By the way, i recommand you get a green screen and some cool background image. This might boost your video quality.
