5 x SW-420 Normally Closed Vibration Sensor Vibration Switch Module
Product Description:
Normal close type vibration sensor SW-420.
Comparator output, signal clean, good waveshape, driving capacity is more than 15mA.
It is used to trigger various vibrations, theft alarms, intelligent cars, earthquake alarms, motorcycle alarms, etc.
Compared to normal open vibration sensor modules, this module can drive relay modules.
How to Use:
1. When the vibration switch is closed, the output terminal will be low, and the green light will be on.
2. If the product vibration, the vibration switch instantly disconnect, the output terminal is high level, the green light is not bright.
3. The output connects directly to the microcontroller via a single chip microcomputer to detect high and low levels, detect whether there is vibration environment, and provide alarm alert.
