Independent transmitting and receiving channels with a single IF output to simplify downstream processing and improve stability. Low power draw at +5 V and 29 mA for efficient operation in controller and sensor applications. Connection and usage Pin 1 VCC: power supply, +5 V Pin 2 IF: intermediate frequency output signal for processing Pin 3 GND: ground Typical integration: provide a stable +5 V supply, connect IF output to an amplifier, comparator, or ADC input for further signal processing. Package contents 1 x Microwave Radar Sensor Module Practical application scenarios Automatic doors: detect approaching people or objects and trigger door opening based on motion and speed. Intelligent lighting control: activate lights when movement is detected in a corridor, stairwell, or outdoor area to save energy and improve convenience. Intrusion detection and presence sensing: detect moving targets near access points or restricted zones and feed signals into an alarm or monitoring system. Compatibility and integration notes Designed as a compact radar transceiver module for integration into electronic control systems, development boards, and custom sensor assemblies. PCB construction and standard pinout simplify mounting and wiring in prototypes and production devices. IF output requires appropriate signal conditioning and processing according to system design. This module provides a compact, lowpower radar sensing option for developers and integrators who need reliable shortrange speed and motion detection without moving parts.
