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

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-520D 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 wide voltage LM393 comparator.

Package Includes :

1 x Normally open vibration sensor module.
