When no vibrations are sensed, it remains closed or in a conduction state. By default, the vibration sensor is in a closed state. The SW-420 is a switch that operates by the opening and closing of the electrical contact.
It passes the digital output of the builtin comparator circuit. It gives power to the sensor.ĭigital output pin. The pin configuration in tabular are detailed below: Pin Name It has three headers for interfacing with any microcontroller.
