The ATMOS 41W integrated meteorological station integrates meteorological sensors, data acquisition and storage, remote transmission control, and power supply system, truly achieving no need for any external lines. Due to the integrated design, the installation of the weather station is extremely simple, and the power supply comes from ordinary No. 5 alkaline batteries or rechargeable batteries, which do not need to be set up and can be activated immediately upon power on. ATMOS 41W is also an IoT device that can view, share, and manage your data from anywhere in the world and on any device by accessing ZENTRA Cloud.

ATMOS 41W collects 10 meteorological elements: total solar radiation, rainfall, air temperature (large, small, and average), atmospheric pressure, vapor pressure, relative humidity, wind speed, wind direction, high wind speed, and inclination. Among them, using optical and tipping bucket modes to measure rainfall results in more accurate data and a wider range. At the same time, it can also measure the electrical conductivity EC of rainfall, helping to distinguish between artificial or natural rainfall.
