Featuring a high- X-band radar chip, this module operates at a center frequency of 10.525GHz, with a detection range of 2-8 meters. It integrates IF demodulation, signal amplification, and digital processing, offering adjustable delay settings for tailored parameter control. Designed for efficiency, the module consumes a maximum of 15mA under normal power supply conditions and only 110uA in pulse power mode. It supports a voltage range of 3.3 to 12.0V and includes a 3-pin interface for easy integration into various applications. Equipped with a directional transmitting and receiving antenna, this sensor ensures focused motion detection within a 110-degree beamwidth. It's ideal for ceiling mounting and operates effectively in environments ranging from -20°C to +70°C with humidity levels of 10 to 95% Rh. The module's output voltage is stable at 3.3V, and it features a power-on stabilization time of approximately 15 seconds. It also includes ESD protection with a typical discharge resistance of 2KV, ensuring durability and reliability in sensitive installations. Customization is facilitated through resistors R14 and R16, which adjust the sensing threshold and delay time, respectively. This allows for precise control over the sensing distance and response time, making it versatile for different monitoring needs. Specifications: Voltage range for matching driver power supply: 3.3~12V Minimum drive current: 1mA (or 100mA) Ripple amplitude: Should be controlled within 100mV Frequency fluctuation amplitude: Should be minimal Installation precautions: Install devices with radar modules away from ventilation ducts, fire pipes, drainage systems, mechanical vibrations, or large metal objects to avoid interference with radar waves and detection accuracy. Safety measures: Avoid working with live electricity to prevent misoperation, connection errors, circuit damage, or . Do not install in areas exposed to direct sunlight or rain to protect the device and extend its lifespan. Electromagnetic interference: Install the device away from strong electromagnetic fields to prevent false activations. Also, avoid areas with fixed rotating or swinging objects (e.g., electric fans, swinging leaves) to reduce the risk of false detections. Installation distance: When installing multiple devices with built-in radar modules, a minimum distance of >0.5m between each device.
