Overview

The RK900-12 Ultrasonic Automatic Weather Instrument is an advanced integrated meteorological monitoring solution developed for reliable and real-time environmental data collection. It combines multiple sensors into a single compact unit, enabling simultaneous measurement of key weather parameters such as temperature, humidity, wind speed and direction, atmospheric pressure, and rainfall. Designed with ultrasonic sensing technology, the device eliminates moving parts, ensuring long-term stability and minimal maintenance requirements.

This weather instrument is powered by a low-consumption chip, consuming less than 1.7W, making it highly suitable for solar-powered or battery-operated systems. Its rugged ASA engineering plastic housing provides durability and resistance to harsh outdoor conditions. Optional modules for solar radiation and illumination further enhance its functionality, making it particularly useful in agricultural meteorology, smart city infrastructure, and environmental monitoring systems. With easy installation and multiple communication outputs, it integrates seamlessly into various data acquisition systems.
