Gravity - microwave sensor for motion detection V2.0 - DFRobot SEN0192

Index: DFR-05497 EAN: 6959420909568

The sensor uses the Doppler effect to detect the movement of objects. By using microwaves instead of infrared, it is possible to detect objects reflecting waves in the microwave range. In addition, the sensor is not dependent on the ambient temperature, it also detects inanimate objects.

Product description: Gravity - microwave sensor for motion detection V2.0 - DFRobot SEN0192

The sensor uses the Doppler effect to detect the motion of objects. By using microwaves instead of infrared, it is possible to detect objects that reflect waves in the micro range. In addition, the sensor does not depend on the ambient temperature and also detects inanimate objects.

Microwave detection has numerous advantages over other methods:

  • Non-contact detection
  • The reading does not depend on temperature, humidity, noise, air, dust or light - suitable for harsh environments
  • High resistance to radio interference
  • Signal harmless to humans
  • Wide range and high speed of detection
  • Detects the movement of inanimate objects

Communication

The sensor is equipped with a digital output, which should be connected to any input of the microcontroller.

The product is compatible with Arduino

Refer to the user guide for an example code and detailed information.

Example of sensor connection. You can download the library for Arduino from the manufacturer's website.

DFRobot Gravity microwave motion detector

DFRobot's Gravity series microwave motion sensor can detect human motion and other physical objects by emitting electromagnetic waves in the radio frequency range. The sensor can operate in a wide range of temperatures, including industrial environments with a high level of pollution. The method of detecting living organisms and inanimate objects using microwave emission is reliable and resistant to external interference. Moreover, the microwave detector is safe for living organisms, i.e. humans and animals.

DFRobot microwave sensor - withstands even the harshest environments

The DFRobot Gravity Series microwave motion detector is an excellent alternative to classic infrared sensors. Unlike IR sensors, microwave sensors have a much higher sensitivity - they are able to detect the presence of people even behind a wall, even when there is no one in the direct field of view of the sensor. Another important practical advantage of such sensors is their high resistance to extreme weather conditions - from bitterly cold temperatures to tropical heat.
