A Raspberry Pi Thermostat built with Java. It uses a DHT11 module to measure the temperature and a relay module to send signals to the AC remote controller.

Raspberry Pi Climate Control

A Raspberry Pi Thermostat that turns an old push button air conditioner into a smart Thermostat. It uses a DHT11 sensor to measure the temperature and a relay module to send signals to the AC controller. Management is done through the web interface where you can see & change the temperature or enable email alerts.

Dependencies

• Java
• Raspberry Pi 2 B+ or above
• DHT11 Temperature & Humidity Sensor
• Relay Module
• Raspberry Pi Camera

Run

$ java -jar Raspberry-Pi-Climate-Control.jar (Web Server Port (Default: 8443))

Run at Startup (Optional)

Add the run command to your RC.LOCAL file. Don't forget to add a "&" after the command so it runs in the background.
