Let’s see how Humidity is doing today…
This arduino controlled LED light changes color when the humidity is not optimal.
Whenever the humidity is below 40%, the color will change to Red
Between 40 and 60% the color will be green
Above 60%, the color will change to Yellow
The humidity is measured with a DHT11 sensor
The lights consists of 4 ( or whatever you like) neopixel lights.
A Arduino Nano is in charge of this battery powered device and the Arduino software is simple and straight forward. It is easy to adjust it to your needs.
