Source: InternetPublisher:刘德华河北分华 Keywords: Infrared remote sensing control circuit trigger Updated: 2020/06/01
Circuit working principle: Infrared remote sensing circuit consists of two parts, namely infrared transmitting circuit
and infrared remote sensing receiving and control circuit . Whenever someone enters or walks out of the hall, the infrared
remote sensing receiving circuit can detect the infrared emission signal returned by the human body, thereby
controlling the circuit output signal and triggering the voice circuit to work.
