ESP8266 WiFi touch screen thermostat

In this project we will show how to build WiFi controlled thermostat with ESP8266, Arduino and touch screen display. Thermostat will also show other info, like weather forecast and temperature outside. Total cost for thermostat is about 40EUR, which is price for basic commercial thermostat in shop.

ESP8266 WiFi touch screen thermostat

Basic features:

  • 6 modes – Auto, Off, LOLO, LO, HI, HIHI
  • Touch screen
  • WiFi connected
  • Four set temperatures (LOLO, LO, HI, HIHI) and weekly schedule
  • Time display
  • Additional data display – temperature in other room, air pressure and weather forecast

Step 1: Materials

  • Arduino Mega 2560
  • ESP8266 WiFi module
  • BMP180 Digital Barometric Pressure Sensor
  • DHT22 Digital Temperature And Humidity Sensor
  • 1 Channel Isolated 5V Relay Module
  • RTC DS1302 Real Time Clock Module
  • 3.2″ TFT LCD Module Touch Panel+ TFT 3.2″ LCD Shield Expansion Board For Arduino

Step 2: Connections

Connect Arduino and TFT shields together. Then add ESP8266 module. Then add ESP8266 to Arduino. See Connenct 5V Arduino and ESP8266 tutorial for details.
