ATMOS 41

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. There are no moving parts to fail. So, installation and maintenance have been simplified to the maximum.

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.

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 EM60G data loggers, you have the flexibility to add any of our other sensors, like soil moisture.

The ATMOS 41 works seamlessly with the EM60G 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…
