Description:
The PIR223W-S0 digital pyroelectric infrared sensor integrates the sensitive element of the traditional pyroelectric infrared sensor with the signal processing chip, and integrates the sensitive element and the IC chip into the sensor shield. The sensitive element transmits the infrared signal generated by the external human movement to the high-precision digital intelligent processing chip for processing by differential input. When the signal processing is completed, the will sensor outputs the signal directly , which is convenient to use.
Feature:
- High precision AD signal processing
- Low operating voltage, low power consumption
- Strong anti-radio frequency interference ability
