The RPTD-627-4-X-F digital pyroelectric sensor integrates the sensitive element of a traditional pyroelectric sensor with a signal processing chip. The sensitive element and IC chip are encapsulated inside the sensor's shield. The sensitive element detects infrared signals generated by human movement and transmits them in a differential input manner to a high-precision digital signal processing chip. After processing, the sensor outputs a 16-bit digital signal for easy use.
