Contact SupplierThe Vibration module based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can be adjusted by the on-board potentiometer. When this no vibration, this module output logic LOW the signal indicate LED light, And vice versa. No shock, vibration switch was closed conduction state, output of low output, the green indicator light. Shock, vibration switch instantly disconnected, the output-side output high, the green light does not shine. The output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting whether the vibration environment, played the role of the police.
