Acconeer A121 pulsed coherent radar chip at 60 GHz, supports presence detection, distance measurement, and motion sensing over SPI
Bus Interfaces
Overview
The LILYGO T-Radar is a compact radar sensor module built around the Acconeer A121 pulsed coherent radar chip operating at 60 GHz. It is designed to be used with other LILYGO motherboards that provide sufficient external GPIO. The module enables contactless presence detection, distance measurement, and motion sensing without the interference limitations of PIR or ultrasonic sensors. It connects over SPI and is fully supported by the Acconeer SDK and open-source Python and embedded libraries.
Use Cases
4Presence Detection
Room-level or zone-level presence and occupancy detection
Distance Measurement
Measuring distances using ultrasonic, laser, radar, or time-of-flight sensors.
home-automation
Industrial Sensing
Industrial-grade sensor applications for monitoring pressure, temperature, vibration, and flow.
