📡 Rd-03 Radar Module with S3KM1110 Chip The Rd-03 is a radar module equipped with the S3KM1110 chip, an integrated single-chip millimeter-wave sensor SoC based on FMCW radar transceiver technology. It operates in the K-band at 24 GHz, with a modulation bandwidth of up to 1 GHz per single-frequency scan to detect targets in the set space using FMCW continuous waves. Combined with advanced radar signal processing, it achieves high-sensitivity motion detection and micro-motion detection. The Rd-03 module senses the presence of a moving or slightly moving human body in the area and provides real-time detection results. It also offers visual configuration tools, allowing easy setup of sensing distance range, sensitivity zones, and unmanned delay time. 📑 Product Details Rd-03 Specification 📌 Pinout Description Pin Number Name Function Description 1 3V3 Input power supply 2 GND Ground 3 OT1 UART_TX 4 RX UART_RX 5 OT2 Detection result output. Outputs high level when sensing, low level when not sensing. 📊 Comparison Parameters Parameter Rd-03_V2 Rd-03_V1 Chip Model Silicon Micro S3KM1110 Silicon Micro S3KM1110 Sensing Range Up to 10m Up to 6.5m Power Supply 3.0V - 3.6V / Current ≥200mA 3.0V - 3.6V / Current ≥200mA Detection Features Human presence detection (motion & static) Motion detection, micro-motion detection Application Scenarios Smart home, security monitoring, energy efficiency Smart lighting, basic motion-triggered automation Rd-03_V2 offers superior sensing with longer detection range and human presence detection, making it ideal for security and energy-saving applications. Rd-03_V1, while effective for motion detection, is better suited for simpler automation needs. 📐 Product Size
