Ai Thinker Rd 03E Sensor

The Ai Thinker Rd-03E is an advanced radar module designed for precise detection and sensing applications. Powered by the silicon micro-S3KM111L chip, this module utilizes FMCW (Frequency Modulated Continuous Wave) radar transceiver technology to deliver accurate human presence detection, motion tracking, and gesture recognition capabilities. Operating in the 24GHz ISM frequency band, it offers superior performance compared to traditional PIR sensors with the ability to detect subtle movements and even breathing patterns. The module features a convenient DIP-5 package with standard 2.54mm pin spacing, making it easy to integrate into various projects. With its wide operating temperature range of -40°C to 85°C, it's suitable for both indoor and outdoor applications. The on-board antenna simplifies installation, while the UART interface ensures easy communication with microcontrollers and development boards. Perfect for smart home automation, security systems, energy management, and IoT applications requiring reliable human detection without privacy concerns associated with cameras.
