Featuring a high-precision 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.
