METER ATMOS 41 – All in One Weather Station

The problem with weather stations

Most weather stations are cluttered, complicated, and frustrating to install and maintain. Wiring and programming all the components can be a nightmare, and finding room to mount everything can be a challenge.

All-in-one weather stations solve many of these problems, but the tradeoff is flexibility. Adding just one more sensor often requires an extra data logger, making the system more complicated and more expensive.

All-in-one plus one

Our solution is an all-in-one…plus one. The all-new ATMOS 41 is the first affordable all-in-one weather station that fulfills all your weather monitoring needs but doesn’t restrain you when you want to do more.

Weather sensors empowered

The ATMOS 41 packages 12 weather sensors into a single, compact device for atmospheric conditions. It was designed for continuous deployment in harsh climates, such as Africa, which means there are no moving parts to fail. Installation and maintenance have been simplified to the maximum because there’s never any mechanical wear. No oiling or replacing bearings. Just reliability you can continue to count on.

Most all-in-one weather stations give you the option to measure solar radiation or precipitation, but not both. ATMOS 41 provides both measurements in one device, so you never have to compromise.

Plus, the ATMOS 41 is accurate. Unlike any other weather station, specialized pins made of real gold measure every single drop of rain. The 0.017 mm resolution means it can accurately measure small rainfall and even heavy dew events that other rain gauges miss. And, no moving parts means the ATMOS 41 anemometer is accurate at low wind speeds. It even has an accelerometer, so you’ll always know the sensor is level and you’re getting accurate data.

Simply smarter

ATMOS 41 weather data (e.g., humidity, temperature, or atmospheric pressure) are transmitted over a single wire. That means you don’t have to use all of the ports on your data logger just for weather measurements. And, if you are using the ATMOS 41 with our ZL6 data loggers, you have the flexibility to add any of our other sensors, like soil moisture.

The ATMOS 41 works seamlessly with the ZL6 for simple, plug-and-play atmospheric data logging and cloud-based data storage and management. You can set up an entire weather monitoring system without any complex wiring or programming.

Weather stations, reimagined

ATMOS 41 is a simple, compact, and connected device with the flexibility to do more than weather measurements. That is why we call it an all-in-one plus one, or two, or three…
