This module has been designed as an alternative to the PIR motion detectors commonly used in burglar alarms. Instead of sensing changes in infrared radio emitted by a moving person this sensor uses a microwave Doppler radar to detect moving objects. It has a sensitivity range of ~7 meters. When triggered its trigger output pin will switch from (LOW) 0V to high (3.3V) for ~ 2 to 3 seconds before returning to its idle LOW state.

Features:

Product code: HCSENS0040
Supply Voltage: 5V dc
Supply Current: >3mA (2.8mA typical)
Operating frequency: ~3.2GHz
Transmit power: 20mW (typical) / 30mW (max)
Size: 36mm x 17mm



Notes:

Component side should face detection area for maximum sensitivity
Do not place metal objects within 1cm of antenna
Trigger out - HIGH (3.3V) motion / LOW no motion
3.3V output is for reference only - do not use to power other devices.
Device operates at ~3.2GHz/20 - 30mW. In some countries it may be illegal to operate this device.



Pinout:

3V3..........Regulated output (reference only)
GND.........Ground / 0V supply input
OUT..........Trigger: HIGH (3.3V) motion detected / LOW (0V) idle
VIN.......... 5V-12V supply input
CDS..........Sensor disable input (pull low to disable)



Schematic:

I don't know if there is a Fritzing part in existence for this module but I'm afraid we don't possess one. Although the image looks a little like a Fritzing part is actually just one of our own drawings.
