  • How Does Doppler Radar Technology Work in This Module?

    Doppler radar works by sending a beam of electromagnetic radiation waves from the transmitter (TX Antenna) and receiving them through the receiver (RX Antenna) and measuring amplitude and position of an object's movement.

    After analysis by a special algorithm, the human body's breathing, movement, number of people, distance, direction, and other information can be obtained.

    What's The Detection Range?

    The area that the radar module measures human activity is within about 200 square meters. The maximum sensing distance for object movement is less than 20 meters and the measurement breathing distance is within 5 meters. The radar antenna has a measurement range of 80 ° horizontally and 30 ° vertically. It is a product that can measure different distances through different algorithms.

    Installation Methods

    By monitoring different detection distances and different motion amplitudes, appropriate deployment is made according to the room layout. When indoors, it will have a better experience when installed at a high place.

    Horizontal Installation

    When installed horizontally, standing or sitting posture is better to monitor. Suitable for office, home appliances, living room, and other open environments.

    In this installation mode, the maximum distance for human motion detection is greater than 10 meters; the maximum distance for human stationary detection is approximately equal to 5 meters; generally the effective action distance is 3 to 4 meters.

    Inclined Installation

    Measure the movement of people in the room. It is mainly suitable for hotels, halls, courtyards, and other environments.

    In this installation mode, the maximum distance for human motion detection is less than 10 meters; the maximum distance for human stationary detection is less than 5 meters, and the effective distance is generally 3 to 4 meters. In this mode, there may be monitoring blind spots directly below the radar and adjacent areas. As the downward-looking angle increases, the static human detection distance will be significantly shortened.

    Top Installation

    Mainly for the monitoring of the human body in the state of lying down, such as bedrooms, nursing homes, hospital beds, etc., can measure a person's breathing state, sleep state.

    Affected by the radar installation height and the radar beam range, the length of the horizontally acting area is about 3 to 5 meters.
