The perfect pack to add to your Classroom Kit. Buy 10 Tilt Sensors and save $51.
This block is fun. It detects motion and can tell other wireless blocks to react. When tilted from side-to-side, it sends a message to turn things on and off. Use it on your door handle to set off an alarm or shake it to flash your LED Light.
Each wireless block has a Bluetooth chip and rechargeable battery inside it. Charging cables not included.
