Vibration Sensor Module SW-420

Vibration Sensor Module SW-420

The Vibration module based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can be adjusted by the on-board potentiometer.

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.

Specifications:
✅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

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
