The BMZ00010 magnetic vibration sensor module uses HOLTEK’s Shock Detector Flash MCU – HT45F56 – to detect the small output signal from the magnetic type vibration sensor. The HT45F56 has a built-in ...

The vibration sensor module is monitored by GP5 (pin 2) of PIC12F675. During the normal condition, GP5 is at logic high (H) state, because of the 10K pull-up resistor. When the motion is sensed, the ...
