The Vibration Sensor Module (SW-420) utilizes the SW-420 vibration sensor and the LM393 Comparator to detect vibrations exceeding a certain threshold. The sensitivity threshold is adjustable via an onboard potentiometer. When there is no vibration, the module outputs a logic LOW signal, and the LED light indicates this state, and vice versa.
If the module is not vibrating, the vibration switch is in a closed state, resulting in a low output and the green indicator light being on. When the module vibrates, the vibration switch momentarily opens, driving the output high, and the green light turns off.
The output can be connected to a microcontroller to detect high and low levels, thereby determining the presence of vibration in the environment and acting as an alarm function.
Note:
Do not reverse the power directions, otherwise, it is possible to burn the chip.
Signal LED light is output Low, signal LED OFF output is High.
The output level close to the input voltage.
