PIR حساس XYC-PIR214D-D0 4 طرف

Description:

The PIR214D-D0 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, A configurable motion detection unit is implemented. Once motion was detected, an interrupt will be send to the host system. Putting the host system to sleep an overall ultra low power consumption will be achieved. All data is accessible from the host system to enable advanced signal analysis with your own detection criteria.
