SW-420 Normally Closed Vibration Sensor Module
Module Purpose:
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, this module takes longer to trigger vibration, and can drive the relay module
Module Features:
1. SW-420 normally closed vibration sensor
2. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA
3. Working voltage 3.3V-5V
4. Output form: digital switching output (0 and 1)
5. Fixed bolt holes are provided for easy installation
6. Small PCB size: 3.2cm x 1.4cm
7. Use wide voltage LM393 comparator
Module Instructions:
1. When the product does not vibrate, the vibration switch is closed and connected, the output terminal outputs low level, and the green indicator light is on;
2. When the product vibrates, the vibration switch is instantly disconnected, the output terminal outputs high level, and the green indicator light is not on;
3. The output terminal can be directly connected with the microcontroller to detect the high and low levels, so as to detect whether there is vibration in the environment and play an alarm role
Product Structure And Wiring Diagram:
Note: The polarity of the power supply cannot be reversed, otherwise the chip may be burned. When the switch signal indicator is on, the low level is output, and when it is not on, the high level is output. The level of the signal output is close to the power supply voltage
