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 41W.

Meet the world's simplest wireless weather station

The ATMOS 41W all-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 telemetry is 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.

More accurate than ever

he ATMOS 41W remote weather station measures 10 environmental variables,
including solar radiation, precipitation, air temperature (min, max,
average), barometric pressure, vapor 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 vapor, air temperature, and wind measurement
capabilities to be more compliant with various meteorological
organization observation standards.
