The Wireless Force/Acceleration sensor W22 simultaneously measures force and acceleration without the inconvenience of wires. The sensor measures force in the range between -80 and 80 N and acceleration along 3 axes x, y, and z, in the range between -16 .. 16 g.
The sensor can be used wirelessly via Bluetooth or wired via USB.

The sensor is equipped with an OLED color display which shows some sensor information and the measured by the sensor values. This makes the sensor suitable to use as an independent measuring instrument.

The sensor can be used wirelessly via Bluetooth or wired via USB with the Coach or Coach Lite programs/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).
