ESP8266 Adds WiFi Logging To IKEA’s Air Quality Sensor

The IKEA VINDRIKTNING is a $12 USD sensor that uses colored LEDs to indicate the relative air quality in your home depending on how many particles it sucks up. Sören Beye tacked an ESP8266 to the board so it can broadcast sensor readings out over MQTT.

All you need to do if you want to perform this modification is solder a couple wires to convenient test pads on the VINDRIKTNING board, then flash the firmware (or write your own version), and you’re good to go.
