Have you tested the measures against a ambient thermometer? I mouted a very similar circuit and I found out that the values are quite different to the actual temperature (more than 2ºC, about 3,6ºF)
Question that I’m having a problem finding an answer to.... I have a couple of 1s lipo batteries with 3 wire connectors. I assume that means they have thermisters. I want to use them on a tiny RC airplane, that only accepts a 2 lead battery. Can I change the connectors on the batteries to 2 lead leaving the 3rd wire on the batteries disconnected, or solder the ground wire to the thermistor wire?
Hi, I am trying to make this work with a ESP8266. I downloaded the library and imported it in the Arduino IDE, copied the thermistor sketch but when I try to compile it, I am getting the error: "In file included from /Users/ap/Documents/Arduino/my_thermistor/my_thermistor.ino:1:0: /Users/ap/Documents/Arduino/libraries/Thermistor/Thermistor.h:19:22: fatal error: WProgram.h: No such file or directory #include "WProgram.h"" Any idea?
It sounds like you haven't installed the thermistor library (or not installed it correctly). There is a link to download it in the description of the video.
thx for the fast reply. I downloaded the github project zip file, extracted it, took the thermistor folder and copied it in the arduino/library folder, restarted the arduino IDE. When I go in Files/examples, I see the thermistor folder and the example sketch (which does not compile either obviously). Is there something else I needed to do to install the library?
Found the issue. I forked the lib and made the fix. I dont know if it is because I am using an ESP8266 or because I am using a newer version of Arduino IDE. Check it out github.com/AlainPilon/libraries
You can use micropython and Esp8266 to read a thermistor, using analog to digital convertion. Using a ESP8266 you will be read a voltaje (0-5v) as (0-1024) value. You can use a micropython with a little script writed in python :). www.techparva.com/index.php/2017/09/01/interface-thermistor-micropython-nodemcu/
sadly no one seems to be getting any answers in here.. but I will ask anyyway.. maybe get lucky. this is not arduino but is thermister. I have 5 devices*..... each with their own very short dongle thermister... possibly 10k.. have not identified yet. though not sure it is relative to this post. wondering if I can snip them off the device(s).. parallel (or would it be series?) connect the two wires of the five device and run run long wires (of appropriate gauge) down a box in area I need to monitor temperature? *device = solar controller.. though not sure if that would matter.... would be same question with 5 arduino boards using one temp sensor to put signal into the board for it to control what ever it does.
why is it when i use other peoples code, it works fine for them, but i always get an error saying somethings not right. whether i retype it, or copy and paste their exact code. its so goddam frustrating. especially as an amateur to electronics, because i dont know how to fix it.
You said "some" of the power.... Well, that is not true. All the power goes though both. The resistor is a pull down resistor. No offense, but maybe a digital electronics class might help you understand a little bit more, but I appreciate the video. ;-)
This tutorial is worthless. You haven’t discussed about the most important aspect about the thermistor about which kind of thermistor and resistor values.

What are the hardware components in the video (mostly the arduino). I'm very new.
What happens if you do not connect the resistor?
you will constantly measure lowest temp, if you do the maths without the library it will be -273.15C.
Do you have the part number for that thermistor? I looking for that size and color in 5K . Regards Luke

I need help too I did the same thing as Alain but when I click include Thermistor it goes but terminator is not orange. Need help
Thermistor . h is not orange
So where is the Thermistor library????
Will this work on esp8266, don't understand how to use linked code for arduino

Same here. Copy+paste=Error☹ all the time.
Make a video explaining how thermistor works.
Your voice raymond reddington :D
can you do this with raspberry pi?
You would need a separate ADC (Analogue to Digital Converter) because the pi won't have one, but technically yeah
