DFRobot SEN0658 Ultrasonic 9-in-1 RS485 Weather Sensor
DFRobot SEN0658 Ultrasonic 9-in-1 RS485 Weather Sensor is a highly integrated, all‑in‑one environmental monitoring solution designed to capture nine essential meteorological parameters with precision and reliability. It simultaneously measures ultrasonic wind speed and direction, air temperature, relative humidity, atmospheric pressure, light intensity, noise levels, PM2.5, and PM10 particulate concentrations, eliminating the need for multiple individual sensors. Using advanced ultrasonic technology with no moving parts, the DFRobot SEN0658 ensures long‑term accuracy, reduced maintenance, and stable performance even under strong winds.
