- Storage Temperature: -40 to 100 degrees Celsius
Adjustment Part Functions:
- C-TM:
- Adjust repeat trigger time by changing the capacitor’s capacity
- Stick capacitor on C-TM for testing and adjust repeat trigger time using the formula: T = (1/f) * 32768, where f is the frequency
- R-GN:
- Adjust detection distance by connecting with a resistor
- Detection distance is 7m without connecting; with a 1M ohm resistor, detection distance is 5m
- R-CDS:
- Enables control of the photoresistor function
- Connects internal VCC to internal 1M ohm resistor to CDS pin for night detection function closure
Pin Definitions:
- 3V3: 3.3V power output
- GND: Ground
- OUT: Control output (high level when motion is detected)
- VIN: Input voltage (4-28V)
- CDS: Enables control chip; low level output on OUT if lower than 0.7V
Installation Tips:
- Avoid placing any metal objects in front of the sensor
- Maintain a minimum 1cm space around the module for optimal performance
The RCWL-0516 Microwave Radar Sensor offers efficient motion detection capabilities with adjustable settings, making it suitable for a wide range of applications.
