RD-03

RF Transceiver Modules And Modems Overview

The Ai-Thinker RD-03 is a standalone 24GHz millimeter-wave radar module designed for high-precision human presence detection. It utilizes FMCW technology to identify micro-movements and motion states, enabling accurate occupancy sensing without requiring data transmission capabilities found in Wi-Fi or BLE variants. The module features a single transmit and receive antenna configuration, supporting both wall-mounted and ceiling-mounted installations with wide detection angles and extended range capabilities suitable for various smart environment applications.

RF Transceiver Modules And Modems Feature Summary

• Detects human micro-movements and motion states using FMCW radar technology
• High sensitivity presence detection that avoids false triggers from non-human objects
• Supports flexible installation methods including wall-mount and ceiling-mount configurations

RF Transceiver Modules And Modems Applications

• Smart lighting systems for automatic on/off control based on presence
• Smart home security and occupancy monitoring
• Environmental monitoring in smart buildings
• Smart security surveillance integration

RF Transceiver Modules And Modems Procurement Notes

Verify the specific hardware revision when sourcing components, as documentation references both Rd-03 and Rd-03D variants which may differ in antenna implementation or chip selection. Confirm compatibility with required UART baud rates and power supply specifications before integration. Ensure that the selected module matches the intended application requirements regarding detection range and installation orientation to avoid performance discrepancies.

RF Transceiver Modules And Modems Selection Notes

Select this module for applications requiring precise human presence detection without wireless connectivity overhead. It is suitable for scenarios where cost reduction is prioritized over data transmission features. Consider the installation environment's complexity and potential interference sources when determining placement. The module's ability to distinguish between human movement and static presence makes it ideal for energy-saving automation tasks.

RF Transceiver Modules And Modems Part Context

The RD-03 belongs to Ai-Thinker's 24G human presence radar series, positioned as a simplified alternative to multi-protocol modules like the Rd-01. It focuses exclusively on radar sensing capabilities, removing integrated Wi-Fi and Bluetooth Low Energy functions to reduce complexity and cost. This specialization allows developers to implement radar-based presence detection in embedded systems without managing additional wireless protocols.
