Standalone Temperature and Humidity Control

Posted on November 11, 2013 by Dushyant in Electronics

Continuing from Standalone Arduino and Thermometer and Humidity Control, created a standalone thermometer and humidity control. Added the following features:

Added a push-button to allow controlling the setpoint temperature
Used the EEPROM library to save the setpoint temperature
Enclosed everything in an extension cord with a power supply
Left a socket to update programming as required
