Vibration Sensor Module (SW-420)

Product Description

• 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.
