The 10.525GHz microwave motion sensor utilizes the Doppler effect to detect moving objects, providing an advanced alternative to traditional infrared sensors. Unlike IR sensors, this microwave sensor is effective across a wide range of reflective materials and operates independently of ambient temperature, making it highly versatile. It is commonly employed in various applications, including vehicle speed measurement, liquid level detection, automatic door operations, and production line monitoring.
The sensor offers significant advantages such as non-contact detection, immunity to environmental factors like humidity, noise, and light, and strong resistance to radio frequency interference. With a detection range adjustable from 2 to 16 meters, it supports both living and non-living object detection. The low power output ensures safety for human users. Ideal for industrial, transportation, and civil applications, this sensor enhances measurement accuracy and is particularly effective in safety and security systems, making it an invaluable tool in modern technology

Applications:

  1. Vehicle speed measurement
  2. Liquid level detection
  3. Automatic doors
  4. Production line monitoring
  5. Safety and security systems

Features:

  1. Non-contact Detection: Works without physical contact.
  2. Temperature Resilience: Unaffected by environmental conditions.
  3. High Sensitivity: Detects both living and non-living objects.
  4. Robust Performance: Resistant to noise, dust, and light interference.
  5. Safe Output: Low power emission, safe for humans.

Package include:

1 x DFRobot Gravity: Digital 10.525GHz Microwave Sensor (Motion Detection)

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
