wireless weather station

ATMOS 41W wireless all-in-one weather station


Most all-in-one remote weather stations claim to be wireless but actually include a wire that connects to telemetry in a bulky enclosure. Add to that a big solar panel and a giant battery, and things start to get costly. We think getting your data shouldn't be complicated or costly. And we think wireless should actually be wireless. That's why we created the ATMOS 41 W.


meet the world's simplest wireless weather station

The ATMOS 41 Wall-in-one remote weather station is one of the world's few truly wireless weather stations, and it's the most affordable research-grade station in its class. It's robust, reliable, and simple to use. All of the telemetries are enclosed with an integrated cell module. But that's not even the best part. There is nothing on the market that is easier to install. Put it in a backpack, take it to your site, secure it to a post pointing North, and walk away. It's that easy to start broadcasting real-time data directly to the cloud.

10 min setup


more accurate than ever

The ATMOS 41W remote weather station measures ten environmental variables, including solar radiation, precipitation, air temperature (min, max, average), barometric pressure, vapour pressure, relative humidity, wind speed, wind direction, maximum wind gust, and tilt. It takes our ultra-reliable ATMOS technology to the next level with a dual rain measurement for higher accuracy and extended range, making it one of the most robust rain gauges on the market. It combines a drop counter and a tipping spoon to ensure accurate measurements, and it's the only rain gauge available that can measure electrical conductivity. Now you can tell if you're measuring rainwater, irrigation water, or if the funnel is plugged with bird droppings. Not only that, we've improved the solar radiation, water vapour, air temperature, and wind measurement capabilities to be more compliant with various meteorological organization observation standards.

10 measurement variables


not plug and play. just play

Forget complicated and costly. If you need a truly wireless, all-in-one, remote weather station that is incredibly simple to install, low maintenance, and can withstand harsh weather conditions, we've got you covered. ATMOS 41W makes scientific-grade accuracy easy and affordable, so you can discover more-and work less.


ditch the setup

We engineered the ATMOS 41W to work right out of the box without having to worry about managing a cell provider or connection, and there's no programming involved. It's a true wireless loT instrument. Put it on a mount, and it's literally sending data to the cloud. What if there's a data transmission interruption? No problem. It has an integrated logger that stores your data, so you've got a backup. Get continuous, 15-minute transmission of high-quality measurements in near-real time. Use ZENTRA Cloud to see, share, and manage your data from anywhere in the world on any device.


low power, low cost, low maintenance

The ATMOS 41W remote weather station was specifically designed for remote areas with harsh weather conditions, so it's tough, durable, requires very little maintenance, and is completely solar-powered, saving you countless trips to your site. An innovative tilt sensor signals out-of­ level condition and no configurations are necessary. It's perfect for microenvironment monitoring, spatially-distributed environmental measurements, crop weather monitoring, fire danger applications, weather networks, and more.
