Arduino 3.2″ TFT touch display and DHT22(AM2302) sensor


This circuit is a part of the home automation system I am planning to build. Currently it reads the temperature and humidity values using the DHT22 sensor and displays it n the TFT screen. Temperature unit can be toggled between C to F by tapping on the temperature label.
