1. the company produced normally closed type vibration sensor SW-420,.
2. the comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma
3. the working voltage of 3.3V to 5V
4. output form: digital switch output (0 and 1)
5. has a fixed bolt hole, convenient installation
6. small board PCB size: 1.2 x 0.5"
7. use the LM393 wide voltage comparator
Note:
1. product no vibration, vibration switch is closed on state, the output terminal output low level, the green light is lit;
2. product vibration, the vibration switch instantaneous disconnection, output the output high level, the green light is not bright;
3. 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 Included::
5 x SW-420 Vibration Sensor Module
