    Description

    RCWL-0516
    Microwave Doppler Radar Sensor Motion Detector Module Board
    The RCWL-0516 is a Doppler radar microwave motion sensor module using the RCWL-9196 IC which is an alternative to a PIR motion sensor such as the HC-SR501 or HY-SRF05. Instead of sensing changes in infrared emitted by a moving person, this sensor uses a microwave Doppler radar to detect moving objects.
    This mini radar motion sensor module is equipped with an RCWL-9196 chip based on the Doppler microwave induction technology. When triggered its trigger output pin will switch from (LOW) 0V to high (3.3V) for ~2 to 3 seconds before returning to its LOW state.   It has a maximum 7 meter (~21 feet) detection distance with adjustable delay time and sensitivity. The detector is not affected by its surroundings, and can operate through glass and other obstructions, providing better performance than traditional infrared (PIR) detectors. It is perfect for DIY microwave motion sensor light switch, security systems, human sensor toys, etc.
    The component side of the board is the main detection side and should face detection area for maximum sensitivity, however, it will also detect from the back side at lower sensitivity. Do not place metal objects within 1cm of the antenna.

    Pin Definition
    3V3: 3.3V power output, can be used as a reference voltage or as a low current  (less than 100mA) 3.3V power supply.
    GND: Ground
    OUT: Control output; when a moving object is detected, it will output high level 3.3V
    VIN: 4-28V Input voltage
    CDS: CDS photodetector output. NOTE: Not used, photodetector is not installed on the board. It can be added by the user for daytime/nighttime detection.
    Adjustment Components
    On the back of the board (the side without components) are pads for 3 optional components (0805 dimensions):
    Pad
    / Function
    C-TM: Regulates the repeat trigger time. The default (unpopulated) time is 2s. An SMD capacitor mounted here will extend the repeat trigger time. Pin 3 of the IC emits a frequency (f), and the trigger time in seconds is given by (1/f) * 32678
    R-GN: The default detection range is 7m, adding a 1M resistor reduces it to 5m.
    R-CDS: Internal
    VCC parallel
    connection with internal 1M Ohm resistor to CDS pin (RCWL-9196 pin 9) through R-CDS. Connects with a photoresistor (not installed on the board, can be added by the user).
