2G GSM / GPRS Sensor Hub for Industrial IoT, Sensor Telemetry, and Remote Monitoring

  • 18800

These sensor hubs uploads your sensor information to in real-time, as often as you need, whether it's every 30 seconds or every 15 minutes.

This GPRS / GSM Sensor Hub made by Yoctopuce is a GPRS / 2G / GSM enabled connector device for Your purchase here includes 1 year of Valarm Tools Cloud / Just tell us the name of your account after you've purchased and we'll credit your account.

This sensor hub connects to any 2G GPRS GSM cellular network, like AT&T or T-Mobile in the states.

You can also connect a GPS sensor to GPS-tag all of your mobile sensor measurements with a location.

The sensor hub hosts up to three Yoctopuce sensors to do remote monitoring of assets, equipment, environmental measurements, and anything else, like:

Each sensor connects to a sensor hub with a Micro B to Micro B USB cable.

You can add as many additional sensors as you like with Sensor Hub Shields. It can be powered either by a USB Micro-B cable and a regular phone charger, or a 5V battery pack.

*** Note: We recommend you use a 3G sensor hub since your mobile cell network provider will support 3G for a longer time than 2G. These other GSM sensor hubs are also available for your organization's Industrial IoT needs:

** Enclosures for these GSM sensor hubs are available here.


How do you link your sensor hubs to

The video above shows you how to integrate your Yocto GSM hub with to map, graph, analyze, download, and forward your sensor data in real-time. 

Use these USB OTG cables to connect your sensors to your sensor hub.

This GSM sensor hub is super useful for mobile Industrial IoT applications when you combine them with GPS / GNSS sensorsTake a gander at this customer story to see how to track and monitor fleet vehicles, trucks, and trailers with industrial equipment and additional sensor factors.

The Yocto GSM / GPRS Sensor Hub Connector Device features a built-in clock timer, that makes it possible to put the device into low-power deep sleep and wake-up automatically at predefined time. This makes it possible to reduce power consumption to 15uA while sleeping, which is crucial for applications running on battery or solar panels. The GPRS GSM Sensor Hub only needs a few seconds of wake-up time to upload sensor data to

Three Yoctopuce sensors can be connected directly, one of which can be fixed directly on the sensor hub and connected using a Board2Board-127 connector. The sensor hub can power Yoctopuce sensors with up to 2A. 

Want to connect more sensors? You can connect as many additional sensors as you like using 1 or more YoctoHub-Shield extensions!

Warning: although the 3 downstream ports hosting Yoctopuce devices use USB micro-B connectors, the sensor hub uses a specific protocol simpler than USB to talk to the devices. Therefore it is not possible to use or even to power a regular (non-Yoctopuce) device using the sensor hub. Also, it is not possible to use a regular USB hub on the downstream ports.
