Quick Features


Aretas brings existing 4-20mA sensors into the IoT Cloud. This 4 Channel Wireless Device can support up to 4 individual 4-20mA sensors at once. The sensor can be powered by the Aretas board or externally loop powered. The data from each of the attached sensors is sent via wireless to an Edge device or Cloud platform. The data can also be exported to other BAS or Automation systems. 

Remote 4-20mA Device Monitoring

You can monitor each 4-20mA device from anywhere in the world. Login to your Edge device or Cloud account wherever you are in the world and see the current device status as well as all the historical data.

Supported Sensors

Industrial Temperature

A wide variety of Industrial temperature sensors available.
  • -40 to 140°F (-40 to 60°C)
  • 0 to 300°F (-18 to 149°C)
  • 0 to 100°C (32 to 212°F)
  • More available

Dew Point

Supporting a wide variety of Dew Point sensors, typical ranges include:
  • -100ºC to +20ºC Dewpoint
  • -60 to 40°C (-76 to 104°F)
  • More available

Airflow / Airspeed

For maximum quality and repeatability, Aretas prefers the Kanomax Air Flow transducers. With typical ranges of  0 – 25m/s and multiple cable lengths. 

Pressure (PSI and kPSI)

Monitor almost any pressure range in an Industrial system. Standard ranges in PSI and very high pressure ranges in the kPSI ranges. 

Vibration / Seismic Velocity

Monitor low and high frequency vibration 

Custom Sensor Options

As long as the sensor outputs a standard 4-20mA signal and we can characterize the sensor output, we can bring your sensor online.

Software Options

Aretas IoT Cloud has full support for analytics, event detection, sensors, real time location and more. Access all your locations remotely, set alerts, view sensor data, add/remove devices and view the status and positions of RTLS objects. 

You can run IoT Gateway v1 with Aretas Cloud V1 or on its own (using the built-in reporting and data storage).

The Aretas Sensor Grapher is a local charting utility that requires an XBee USB adapter and a PC with Java installed.
