This isn’t about connecting a temperature sensor in your Arduino. ... The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.
It’s a simple piece of hardware based around a Dallas DS18B20 1-wire temperature sensor and an ESP8266 module, powered by 3 AA batteries and passing its data to data.sparkfun.com.
Each sensor has a unique 64-bit device number. The Arduino code pings the Dallas sensors and receives a coded data stream from each one containing the device number and temperature reading. The Dallas ...
I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...
