Description

Vibration sensor is a MEMS sensor and microcontroller-based intelligent signal processing system. Its system designation is based on the principle that the cutting of concrete, steel or syhthetic materials such as metal shell will cause changes in the structure of vibration. these changes in vibration sensor can be converted into electronical signals, while the vibration sensor analyse the signal with digital signal processing module. and compare it with the general frequency range of detection equipment. If it exceeds the normal range, vibration sensor will alarm through relay contacts. Advanced signal processing technology can distinguish external noise and real attacks. Three-dimensional exploration. Vibration sensor collects three dimensional orientation of the vibration signal in real time (acquisition once every millisecond), and analyze to compare with the vibration amplitude that is set. Once exceeded, it would be associated with the output switching signal to trigger other devices linkage.
