LDRR04S is an ultra‑compact 80GHz FMCW radar ranging module designed for professional hydrological detection. It provides non‑contact, high‑accuracy distance measurement ideal for rivers, lakes, reservoirs, flood warning, and sewage pipe networks.
This 80GHz radar module offers a 0.1–20m measurement range, with ±3mm accuracy and 1mm resolution, delivering stable data even in harsh environments. Fast startup within 100ms and adjustable refresh rate (0.1–25fps) support real‑time monitoring.
With 3.3–5V DC low voltage input and only 27mA typical current, it is highly power‑efficient for battery‑powered systems. The module supports UART output (115200 baud rate) with ASCII/Modbus dual protocol, enabling easy integration with IoT and telemetry systems.
Measuring only 35×35×1.2mm and weighing 5g, this tiny module fits into space‑limited devices. It works reliably from -45°C to +85°C with strong anti‑interference, perfect for outdoor unattended monitoring.
Whether for water level monitoring, liquid level detection, industrial ranging, or flood early warning, the LDRR04S 80GHz radar module brings high precision, small size, and stable performance to your project.
