S23-S330Y mini SMD AD PIR sensor

S23-S330Y pyroelectric infrared sensor is a SMD AD pyroelectric infrared sensor. The core component of the sensor is composed of three parts: pyroelectric detection sensitive element, infrared filter and AD chip. The human body detection sensitive element transmits the sensed human body movement signal to the AD chip, which outputs 16-bit digital signals through acquisition, filtering, etc., and realizes related functions through the single-chip microcomputer of the peripheral circuit.
