The LILYGO T-Radar V1.0 revolutionizes proximity sensing with its Infineon A121 pulsed coherent radar (PCR) chip, delivering absolute distance accuracy within ±1mm across its 20-meter operational range – a benchmark previously unattainable for compact IoT modules. Engineered for dual-sided integration, its PCB features clearly labeled front-side pins () and reverse-side power inputs (), enabling plug-and-play connectivity with ESP32 or Arduino controllers via high-speed SPI communication.
Uncompromising Sensing Capabilities leverage 60GHz millimeter waves to penetrate drywall, fabric, and plastic while resisting environmental interference like darkness, fog, or glare. This allows the module to achieve µm-level relative precision for detecting subtle movements, including respiratory patterns or micro-vibrations, far outperforming optical/PIR alternatives.
Industry-Defining Applications
Sports Analytics: Track ballistic objects or athlete kinematics in real time.
Industrial Automation: Classify materials (metal/wood/plastic) and monitor object displacement down to ±0.1mm for robotic assembly lines.
Healthcare Innovation: Enable non-contact respiration and pulse monitoring (12–30 BPM detectable through barriers).
Smart Security: Detect human presence behind walls for intrusion alerts or occupancy-based automation.
