Get Copy Board Failure Board Safe Burglar Alarm Electronic Competition Training DIY Kit Features: The safe anti-theft safety circuit, theft of thieves, fire and smuggling can be alarmed by alarm to prevent loss in time. Working principle   1.Sensor Y1 vibration sensor (piezoelectric sensor) BZ mercury switch sensor RT temperature sensor   2. Detection circuit (1) Pry detection alarm circuit When the safe is subjected to vibration, the piezoelectric sensor Y1 will sense the voltage signal, which will be amplified by VT1 and then amplified, and will be transmitted to pin 3 of the dual D trigger U5. foot. (2) sport detection alarm circuit It can detect whether the safe is tilted due to moving. When tilting occurs, the mercury sensor BZ is turned on, and a high-level signal is transmitted to pin 5 of the OR circuit U3. (3) Flame cutting detection alarm circuit The thief opened the safe by means of flame cutting, the thermistor RT detected a temperature rise, and the comparator U4 output a
