When STEMlab is used together with this sensor extension module the user is also able to connect many sensors and actuators that enables out of the box functionality. You can measure temperature, moisture, alcohol, water level, vibrations, UV light, sound, pressure, air quality detect motion. Also you can control things like LEDs, displays, motors, relays that are able to control high load devices. The sensor extension module is ideal for both newcomers to help them learn how to program and for developers to manufacture their new ideas quickly.
