ATMOS 41 Weather Station

The METER ATMOS 41 is a modular micro-environment weather station that has no moving parts and a slim, tubular form factor.

  • The ATMOS 41 weather station measures 12 weather variables including:
    • air temperature, relative humidity, vapour pressure, barometric pressure, wind speed and direction, solar radiation, precipitation, lightning
  • Easy installation
  • No moving parts
  • All data transmitted over a single wire
  • Digital SDI-12 communication

It can be connected to ICT Loggers via SDI-12, ideal for use with the ICT SDI-12 Logger as a simple, fully featured 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 trade-off 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.

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


Utilising the ATMOS-41 Sensor in a custom IoT (Internet of Things)

The SNiP-A41 is a ‘Sensor Node Integrated Package’ for LoRaWAN or CAT-M1 communication of real-time weather parameters for continuous environmental monitoring.

The SNiP-A41 integrates 1x ATMOS-41 Sensor with an S-NODE to a site’s unique network, communication and power requirements. The S-NODE can support an added 3x compatible sensors.

The ATMOS 41 packages 12 weather sensors into a single, compact device. 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 data 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 METER’s new ZENTRA ZL data loggers you have the flexibility to add any of METER’s other sensors, like soil moisture.

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