Human infrared thermal release alarm

Published:2011/9/26 22:01:00 Author:Rebekka | Keyword: Human infrared, thermal release alarm

Human infrared thermal release alarm can receive the heat releasing infrared ray issued by the body during the day or night, then it willgive the sound and light alarm. It is ideal for electronic guard. Working principle: The circuit uses imported IC, general-purpose sensor control circuit, high input impedance operational amplifier, it consists of the timer, the timer latch, and the operating voltage is 3.5V ~ 5V, and quiescent currentis 60μA. It uses 3 ~ 4 1.5V batteries or 6V ~ 12V rectifier. Pyroelectric infrared sensor RIP09 TL receives body heat release signal. The signal will be amplified by the first stage op amp in IC. Then it will be amplified and coupled by the second level of C6 amplifier. Then it will be sent to built-in comparator to have bidirectional amplitude discrimination. R2, C2 are delay control. If you need longer hours of work, you can increase the R2's resistance or the capacitance value ofC2, the circuit is set to 3s ~ 4s.   (View)
