TheNose

TheNose is a gadget for monitoring in-door air quality and visualizing it with a RGB LED shining through the tip. In addition, the data is saved to a MQTT broker in the local network, so that all values are available on a Node-Red dashboard. The electronics consists of an Adafruit SGP30 air quality sensor breakout board, an Adafruit si7021temperature and humidity board, and finally an additional prototyping board carrying the ESP8266 controller as well as the LED and a voltage regulator.
