Unlock comprehensive environmental insights with a single, robust device. The Ultrasonic RS485 9-in-1 Weather Station Sensor delivers precise data on nine critical meteorological parameters (wind speed, wind direction, air temperature, relative humidity, atmospheric pressure, light intensity, noise levels, PM2.5, and PM10), eliminating the need for multiple individual sensors. Ideal for Arduino projects, agricultural management, and smart city applications, it provides a complete picture of local weather conditions.
Comprehensive & Accurate Multi-Parameter Sensing
Obtain a complete and precise environmental overview with this all-in-one sensor. It simultaneously measures ultrasonic wind speed, wind direction, air temperature, relative humidity, atmospheric pressure, light intensity, noise levels, PM2.5, and PM10 particulate matter. The advanced ultrasonic technology for wind measurement ensures superior accuracy and durability with no moving parts, minimizing wear, eliminating on-site calibration needs, and offering reliable performance even in strong winds for lower maintenance and extended service life.
