PIR Sensor XYC-PIR223D-S0 3 Pin

From the shop's description

Description: The PIR223D-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 Schmidt output, strong anti-interference ability Low operating voltage, low power consumption Specifications: Maximum Ratings: Parameter Symbol min max unit Input voltage Vdd -0.3 4.5 V Pin current Into -100 100 mA Storage temp Tst -40 85 ℃ (T=25℃) Working Condition ： Parameter Symbol min typical max unit note working voltage Vdd 2.7 3.3 3.7 V working current Idd 10 uA 3.3V\25° Sensitivity threshold Vsens 110 uV unadjustable working temperature Wst -20 70 ℃ Output Output Low Current Iol -5 5 mA Lock Time 2.3 S unadjustable Delay Time 1 S unadjustable Product Dimension： Pin Description： 1 VDD Power supply pin 2 Rel Output pin, output TTL high and low electric level 3 Vss Power ground GND Detection Angle： Application Applicable to all types of automatic lighting switches Applicable to all kinds of intrusion detectors for burglar alarms Applicable to all kinds of smart toys Applicable to all kinds of smart household appliances Datasheet
