What exactly is the “IoT Fabric” VersaSense is talking about?

Whereas most vendors in the IoT space are focused on providing “edge-to-cloud intelligence”, VersaSense is focused on solving the more difficult problem of providing “sensor-to-edge connectivity”. We provide the wireless fabric to capture asset data, either through our sensors or through interfacing to existing or legacy sensors, and deliver it seamlessly to the backend systems. The plug-and-play nature of the VersaSense IoT Fabric enables our customers to connect, in a reliable and secure way, a wide variety of assets in a matter of hours, not weeks or months.

How can I connect existing or legacy sensors to the VersaSense IoT fabric?

To connect legacy sensors, VersaSense provides several interfaces. We provide support for legacy sensors that have certain standard outputs such as for example:

  • current loops (*), through the MicroPnP Current Loop Interface (S24)
  • direct current (DC) voltage, through the MicroPnP DC mV Sensor (S25)

In addition to the above, several interfaces are available for specific sensors by providing support for RTDs, thermistors, thermocouples, strain gauges or general-purpose binary input.

How does VersaSense achieve battery life of up to 5 to 10yrs for its IoT devices?

Battery life of 5 to 10 years can be achieved by a combination of careful battery selection, energy optimized hardware, synchronized radio network and device sleep as well as careful tuning and implementation of software features. All VersaSense devices are energy optimized and validated on the test bench before being released for sale. Finally, all VersaSense devices have a managed battery pack that allows lifetime information to be consulted at all times on the dashboard.

How does VersaSense achieve end-to-end security for its IoT fabric?

The VersaSense approach to security combines certified cryptography, to guarantee confidentiality and integrity, with next generation key management and certified code updates to provide best-in-class security.

For more detailed information on the best-in-class security implemented through the VersaSense solutions, please check out our White Paper “Secure Plug-and-Play Sensing and Control for the Industrial Internet of Things (IIoT)”, which you can find on the Resources section of the website (Click here).

What is the typical range I can expect for VersaSense wireless devices?

For devices in a mesh network, based on the SmartMesh IP technology from Linear Technology, now part of Analog Devices, the range one can expect depends on the specific situation but in general ranges from 35 to 50m indoor and up to 100m outdoor.

For devices based on the LoRaWAN specification outdoor range is in the 10 to 20km scope depending on the environment and placement of LoRa base station.

For which major IoT Platforms does VersaSense provide out-of-the-box connectors?

VersaSense provides connectivity solutions to cloud based IoT platforms including:

  • Altizon Datonis IoT Platform
  • Microsoft Azure IoT Hub
  • InfluxData Time Series Platform
  • Various cloud platforms such as IBM Watson™ IoT Platform or Amazon AWS using MQTT

This connectivity is offered through out-of-the-box software connectors running on the gateway. Furthermore, VersaSense can also provide connectors for other IoT platforms through its professional services team.

How can I evaluate the VersaSense IoT solution in my own environment?

You can acquire an Evaluation & Development Kit from our global distribution partner Digi-Key. The kit provides you with an IoT gateway, two wireless devices and a basic set of sensors for light, temperature, humidity, infrared, a buzzer actuator and a programming peripheral.
