Camp Information

Environment Monitoring Camp

In this camp the girls will be using a microcontroller and environmental sensors for indoor monitoring. They will measure temperature, humidity, and air quality. It's great for keeping tabs on what's going on in rooms in your house, office, or elsewhere. They will learn to push the data to the Adafruit Internet of Things cloud allowing us to view the data remotely from anywhere. It is going to be cool.
