Vibration/Shock Sensor module

This is Vibration/Shock sensor module can be used for various vibration trigger functions, including reported theft alarms, smart cars, electronic building blocks, and more. Please be aware that normally open vibration sensor modules may induce a very slight vibration when the trigger time is very brief, which is insufficient to operate the relay and renders some information displays ineffective when connected directly to the relay module. While the product is not vibrating, the vibration switch is kept in the off position, the output is high, and there is no green light. But, when the product is vibrating, the vibration switch enters the momentary conduction mode, the output end is low, and there is a green indicator light. SW-18020P Vibration Sensor is a really simple vibration switch, it is used commonly in electronics toys, alarm, domestic appliance, electronics devices, smart home system.
