Uses:
For a variety of vibration the triggering effect reported theft alarm, smart car, earthquake alarm, motorcycle alarm.
Compared to the module with normally open type vibration sensor module, vibration, longer trigger relay module can drive
Module Features:
SW-420 using the company’s production of normally closed type vibration sensor.
The comparator output, the signal is clean, the waveform, the driving ability to exceed 15mA
Operating voltage 3.3V-5V
The output in the form: Digital switching outputs (0 and 1)
A fixed bolt hole for easy installation
Small board PCB size: 3.2cm x 1.4cm
Wide voltage LM393 comparator
Module using the instructions:
The product does not vibrate, vibrate switch was closed conduction state, the output output low, the green indicator light;
Product vibration, vibration switch instantly disconnect the output output high, the green light is not on;
The output and the microcontroller is directly connected to the microcontroller to detect high and low, thereby detecting the vibration environment, play an alarm role
