SW-420 Alarm Vibration Sensor Module - (AD30653)

Description:

It is used in a wide variety of shock trigger effects, burglar alarms, smart cars, earthquake alarms, and motorcycle alarms. The vibration sensor module is normally open when subjected to vibration.

Characteristics:

- The SW-420 sensor is a Normally Closed type.

- The comparator output signal is clean, good waveform, easy to control, consumes more than 15mA.

- The working voltage is 3.3V to 5V.

- Output format: Digital switching [0 - 1].

- Has mounting hole for easy installation.

- PCB Size: 3.2cm x 1.4cm.

- Uses the LM393 as a comparator

How to use:

1. If the switch is NOT subjected to vibration, it is in the closed state, i.e., conducting, so the output is LOW; the red indicator light is active.

2. If subjected to vibration, the switch is instantly disconnected, the output is HIGH, the red light goes off.

3. The output can be directly connected to the microcontroller to detect high and low, which detects the vibration environment.
