Normally Open Vibration Sensor Module SW-1801P Alarm Module High Sensitive Vibration Switch ModuleItem NO.: SW-1801P

Vibration Sensor Module SW-1801P Alarm Module

Product Use:

It is used for various vibration triggering functions, theft alarm, smart cars, electronic building blocks, etc.

Please note that the triggering time of this module will be very short when it senses a small vibration, which is not enough to drive the relay. Some people's information shows that it can be directly connected to the relay module. The actual application effect is not good. The store does not want to mislead consumers.

Module Features:

1. The high sensitivity vibration switch produced by our company is used, and SW-1801P vibration sensor is used by default,.

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 Wiring Instructions:

1. VCC: connected to the positive pole of power supply

2. GND: connected to power cathode

3. DO: Digital signal output

4. AO: This function is invalid with this vibration sensor

Module Instructions:

1. When the product does not vibrate, the vibration switch is disconnected, the output terminal outputs high level, and the green indicator is not on;

2. When the product vibrates, the vibration switch is turned on instantaneously, the output terminal outputs low level, and the green indicator light is 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
