Product Information
SW-420 vibration sensor module vibration switch alarm sensing module
Model Number: M2021014
Advantage
Comparator output, clean signal, good waveform, strong driving ability, more than 15mA,Use wide voltage LM393 comparator
Working Voltage
3.3V-5V
Output
digital switching value output (0 and 1)
Installation
Fixing bolt holes are provided
Size
3.2cm*1.4cm
Application
It is used for various vibration triggering functions, theft alarm, intelligent car, earthquake alarm, motorcycle alarm, etc. Compared with the normally open vibration sensor module, the vibration trigger time of this module is longer and can drive the relay module
Instructions
1. When the product does not vibrate, the vibration switch is closed and on, the output end outputs low level, and the green indicator light is on. 2. When the product vibrates, the vibration switch is momentarily disconnected, the output end outputs high level, and the green indicator light is not on. 3. The output end can be directly connected with the single chip microcomputer to detect the high and low levels through the single chip microcomputer, so as to detect whether there is vibration in the environment and play the role of alarm
