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 ...

Nice method and analysis. 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.

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

It’s noteworthy that the temperature sensor socket’s pin assignment is in the correct order for DS18B20 only. When using LM35, the sensor must be inserted correctly — i.e., in the inverse direction ...
