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 disconnect due to conductive rolling ball inside to generate changing signal in the circuit, and restore to open-circuit when the excitation is removed.
Single-roller type full induction trigger switch. When no vibration or tilt, the switch is in ON conduction state, and in the steady state, when a vibration or tilt, the switch will be rendered instantly disconnect the conductive resistance increases, generating a current pulse signal, thereby triggering circuit.
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.
