Human body sensor automatic alarm circuit
Source: InternetPublisher:子丑寅卯 Keywords: Human body sensor alarm circuit automatic alarm induction type Updated: 2021/10/02
Circuit working principle: The alarm
is composed of four parts: infrared controller (VTO, IC1), level conversion transistor VT1, delay control circuit IC2 and alarm circuit.
When a thief appears in a certain area, the infrared rays radiated by the human body are
received by the probe VTO infrared sensor and converted into electrical signals.
After being processed by the internal circuit of IC1 (CK-7), a high level is output on pin 2 of IC1 (CK-7).
