This Normally open vibration sensor module is for a variety of vibration trigger functions, reported theft alarms, smart cars, electronic building blocks, and so on. Please note that Normally open vibration sensor module is in the induction of a small vibration when the trigger time is very short, and not enough to drive the relay, some of the information displayed can be directly connected to the relay module, so the actual use of ineffective.

When the product does not shake, the vibration switch is held in an off state, the output is high and the green light does not shine when the product vibrates, the vibration switch goes into momentary conduction mode, and the output end of the output goes low and the green indicator light-up.

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.

Features :

1. Using the company's high-sensitivity vibration switch, the default with SW-18015P vibration sensor.
2. The comparator output, the signal clean, good waveform, driving ability, more than 15mA
3. With a fixed bolt hole, easy to install.
4. The use of a wide voltage LM393 comparator.
