Mantis Open STEM Sensors

Mantis Open STEM Connects to Scratch

The Mantis Open STEM family of sensors is able to connect to Scratch. The sensor data is availble to Scratch in real time.


The Mantis Climate Sensor tracks air temperature, humidity, pressure, and sunlight intensity for the day or for several months! Having the weather station running in the classroom opens up conversations about meteorology topics.


The wireless Bluetooth connection allows Climate Sensor to be placed in sealed jars, refrigerators, etc. to perform experiments to observe how our atmosphere behaves in accordance with the gas laws.


The Mantis Modi is an accelerometer, gyrometer, and distance sensor. Its small size and wireless connection make it ideal to run motion experiments such as tracking the motion of a spinning bicycle wheel:
