PRODUCT DESCRIPTION
This module serves as a normally open vibration sensor, ideal for various applications such as triggering theft alarms, controlling smart vehicles, or building electronic projects. It’s important to note that this sensor only detects minor vibrations briefly, which is not sufficient to activate a relay. Therefore, connecting this module directly to a relay is ineffective.
When stationary, the vibration switch remains off, resulting in a high output signal, and the module’s green light stays unlit. Upon detecting vibration, the switch activates momentarily, causing the output signal to drop to low and the green light to flash.
By connecting the output to a microcontroller, you can monitor the high and low states, enabling the detection of vibrations in the environment and triggering an alarm if needed.
Connection
VCC: Connect the positive power supply
GND: Connect to the negative power supply
DO: The digital signal output
