• Tweet
• Pin It

This project aims to monitor the temperature and humidity in a room, through a compact and cheap device, powered via USB and which sends data to our smartphone through WiFi communication.

The circuit consists of an ESP8266 module, a DHT22 temperature and humidity sensor and a 3.3V voltage regulator. The ESP8266 module will connect to our WiFi network and send the data through the Blynk service. Thi service will allow us to view the data from the sensor, conveniently on a smartphone using the appropriate app.
