RCWL-0516 Microwave Radar Sensor Module Human Body Induction Switch Module

Input and Output:

• Output Signal: Digital high/low signal
• Pins:
  • VCC: Power input (4V to 28V)
  • GND: Ground
  • OUT: Digital output signal (high when motion is detected)
  • CDS: Input for connecting a light-dependent resistor (LDR) for day/night detection
  • VIN: Optional power input for logic level (3.3V to 5V)

Physical Characteristics:

• Dimensions: Compact module, typically around 36mm x 17mm x 9mm
• Weight: Lightweight, generally a few grams
• Antenna: Integrated on the PCB

Additional Features:

• High Sensitivity: Detects motion through walls, doors, and other obstacles
• Low Power Consumption: Suitable for battery-powered applications
• Day/Night Detection: Supports connection of an LDR for light sensitivity adjustment
• Adjustable Sensitivity: Sensitivity can be fine-tuned using onboard components
• Easy Integration: Simple to connect to Arduino, Raspberry Pi, and other microcontrollers
• Applications: Ideal for human presence detection, security systems, motion-activated lighting, and automatic door openers.
