Parts and tools Arduino UNO LM35 Temperature Sensor (Celsius) – datasheet Relay Module ( May refer to my previous post on how to make a relay module) A 9V battery (To supply to the coil of relay and ...

By the way, we’ve covered a PID library for Arduino before. While this post talks about temperature, PID control is used for everything from flight control to levitation.

[Jens]’ device consists of an Arduino, LCD display, and two sensors – one for acetone, and another for temperature and humidity.

This project uses a $30 Arduino Uno R3, an RGB LCD display, a waterproof temperature sensor, food grade heat shrink, and a few other components, all of which are available at the link below from ...

The LCD display showed moisture, temperature, and light readings in variable resistance values, so I needed to calibrate the data to understand what it all meant.

The arLCD is a smart 3.5" color touchscreen LCD Arduino combo board that brings easy-to-program, smartphone-like user interfaces to the Maker Community. Release 2.0 is endorsed by Arduino by being ...
