PRODUCT DESCRIPTION
This module is a normally open vibration sensor that can be used for various purposes, such as triggering a theft alarm, controlling a smart car, or creating electronic building blocks. However, please be aware that this module only detects small vibrations for a very short time, which is not enough to activate a relay. Some information may suggest connecting this module to a relay directly, but this will not work effectively.
When the product is still, the vibration switch is off and the output is high. The green light on the module stays off. When the product experiences a vibration, the vibration switch turns on momentarily and the output goes low. The green light on the module flashes.
The output can be connected to a microcontroller to monitor the high and low levels of the output. This way, the microcontroller can detect whether there is any vibration in the environment and trigger an alarm accordingly.
Connection
VCC: Connect the positive power supply
GND: Connect to the negative power supply
DO: The digital signal output
