MH Sensor Series

This is an easy to use sensor module you can use to sense very small vibration, shock or knock onto it. Upon being vibrated, the switch will momentarily short-circuit due to spring mechanisms inside to generate changing signal in the circuit, and restore to open-circuit when the vibration is removed.

Note : this sensor can works with both analog and digital mode. You can use its analog output (AO) to get the intensity reading or digital output (DO), adjust the potentiometer (a.k.a. trimmer) to set the digital output sensitivity.
