Pir0001 is a special chip for infrared induction control of human body designed for LED lighting, which adopts advanced COMS
It is suitable for the application of photosensitive triode or photosensitive resistor (CDS). The chip has a stable power supply with high performance.
Voltage circuit, operational amplifier, voltage comparator, timer, control circuit, system oscillator, and output setting
Time oscillator, PIR sensor transforms the change of infrared signal generated by human activity into voltage signal
According to the standard of the amplitude of the output voltage signal, the change of No.
Characteristic
Working voltage: 3.6V ~ 5.5V, built-in voltage regulator: 3.0V ± 0.36v.
§ 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 a delay time of 16 seconds for output
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.
