D203S PIR Infrared Radial Sensor Human Motion Detector
Excellent performance infrared sensor for use in alarm burglar systems, visitor presence monitoring,
light switches and robots. Narrow detection beam for use in hallway and defined area detection systems.
Dual Compensating Elements
Excellent Operating Stability
Supply Voltage: 3-15V
Narrow Sense Window for Directional Sensing
Body Dimensions: 9.1mm Diameter, 4.5mm High excluding pins, Pins - 13.5mm High
As indicated in the following diagram, PIN#3 of the sensor should be connected to
the ground or the negative rail of the supply.
Pin#1 which corresponds to the "drain" terminal of the dvice should be connected to the
positive supply, which must be ideally a 5V DC.
And pin#2 which corresponds to the "source" lead of the sensor must be connected to ground
via a 47K or 100K resistor. This pin also becomes the output pin out of the device and the
detected infrared signal is carried forward to an amplifier from pin#2 of the sensor.
