The Ai-Thinker RD-01 Human Presence Sensor with WiFi & Bluetooth is a highly advanced radar-based detection module designed for smart automation, security, and IoT applications. Utilizing FMCW (Frequency Modulated Continuous Wave) radar technology operating at 24GHz, it accurately detects both human motion and micro-motion—even when subjects are stationary. This gives it a major advantage over conventional PIR sensors that rely only on movement. The RD-01 integrates Wi-Fi 802.11 b/g/n and Bluetooth 5.0 (BLE) for seamless wireless connectivity, enabling real-time data transmission and configuration through IoT platforms. With its multiple interfaces including UART, GPIO, ADC, PWM, I2C, and SPI, it offers flexible integration into various embedded systems. The module’s energy-efficient design makes it perfect for battery-powered applications, while its compact form factor ensures easy installation in tight spaces. Whether for smart homes, security monitoring, or industrial automation, the Ai-Thinker RD-01 delivers next-generation human presence detection with high sensitivity, reliability, and wireless flexibility.
