Rd-03E is a radar module equipped with the S3KM111L chip that operates in the K-band at 24GHz with a modulation bandwidth of up to 1GHz per single frequency scan.
The module uses FMCW waveforms and proprietary advanced signal processing technology, combined with the MCU's proprietary radar signal processing and built-in intelligent presence sensing algorithms, to achieve accurate human sensing distance measurement and gesture recognition.
The developer can display the distance information and gesture information in real time through the host computer tool.
The Rd-03E module can detect, identify and report the real-time distance of the moving and micro-moving human body, detect targets and gestures in the designated area and report the results in real time, which is widely used in various AloT scenarios.
The module has the features of strong real-time, high distance measurement accuracy, large range of distance measurement, and flexible configuration of algorithm parameters.
