Product no vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit
Product vibration, the vibration switch instantaneous disconnection, output the output high level, the green light is not bright
Output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect whether there is a vibration environment, call the police
Package include: 1x SW-420 Module
