Pyroelectric infrared sensor controller PIR0002

Pir0002 is a special chip for infrared induction control of human body designed for AC relay application, which adopts advanced
COMS technology is suitable for the application of photosensitive triode or photosensitive resistor (CDS). The chip is equipped with high-performance electricity.
Source voltage stabilizing circuit, operational amplifier, voltage comparator, timer, control circuit, system oscillator, and transmission
The PIR sensor converts the change of infrared signal generated by human activities into electricity.
According to the amplitude standard of output voltage signal, the change of voltage signal determines whether the relay is closed or not and the transmission
Output time is adjustable.
Characteristic
Operating voltage: 2.2V ~ 5.5V
§ built in system clock frequency: 16KHz
Operating current: < 20ua (Vbat = 4.5V, no load)
Support phototriode or photoresistor to detect the brightness of the environment, so as to judge the current time is
Day or night
Provide external RC set output delay time for 3 seconds to 110 adjustable
After power on, the power supply has a stable time of 1 second and a warm-up time of 16 seconds (warm-up time).
The output has a signal inhibit time of 1 second from on to off.
