Vibration Sensor Module Normally Opened Type

Vibration Sensor Module Normally Opened Type is based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can be adjusted by the on-board potentiometer. When this no vibration, this module output logic LOW the signal indicate LED light,And vice versa.

The product when it is not shock, vibrate switch is closed on-State, output output low level, the green indicator light is on; When vibration, vibration switches disconnected moments, output line, the Green led is not lit; the output can be directly connected to the micro controller, by single-chip computer to detect high or low level, to detect whether there is vibration, alarm function

Output can be directly connected to the microcontroller through the microcontroller to detect high and low levels, thus to detect whether there is a vibration of the environment, play an alarming role.
