Quick Features


Aretas wireless temperature and relative humidity monitors are available in many configurations. Our standard digital T+RH monitors are accurate to 0.2C and +/- 1% RH. We also support industrial high temperature applications and freezer monitoring. Ultra high precision sensors are available. Non-contact thermal monitoring also available

Remote Temperature and Relative Humidity Monitoring

You can monitor conditions from anywhere in the world. Login to your Edge device or Cloud account wherever you are in the world and see the current temperature, relative humidity, alerts and all the historical data from any device in your account.


MDU / Residential

Monitor unattended properties or tenant occupied properties. Prevent property damage or excessive heating bills. 

Commercial Offices

Monitor Temperature and Relative Humidity and utilize the Aretas analytics suite to find optimizations for energy savings, occupant comfort, heat index and more. 


Deploy wireless high temperature monitors or bridge existing 4-20mA temperature measurement equipment into the Cloud and benefit from online analytics and datalogging solutions. 

Food Processing and Sales

Monitor fridge and freezer temperatures to ensure food is stored or processed under optimal conditions. Receive alerts when fridge or freezers are left open. 

Datacenters / Containers

Server rooms, datacenters and containers all require reliable ventilation to prevent servers from overheating. You might know the internal temperature of your servers, but knowing the ambient temperatures can tell you where temperature issues originate so you can take preventative action before valuable server equipment is damaged.

Electrical Rooms / Industrial Control Rooms

Electrical rooms in an Industrial setting, such as a sawmill, granary or food manufacturing facility, where high voltage panels are installed, need to have positive pressure to keep out combustible dust and contaminants.
