Description

MH Sensor Series

This is an easy to use sensor module you can use to sense very small tilt (rotation), as well as vibration, shock or knock onto it. Upon being excited, the switch will momentarily short-circuit due to conductive rolling ball inside to generate changing signal in the circuit, and restore to open-circuit when the excitation is removed.

Note : this sensor can works with only DIGITAL mode. You must adjust the potentiometer (a.k.a. trimmer) to set the digital output (DO) sensitivity.
