Valarm Tools Cloud GPS Antennas GSM Hub Sensor Telemetry Real-Time Tracking Vehicles 2A warm welcome goes out to the latest sensor hubs compatible with Valarm Tools! The GSM sensor hub connects your remote monitoring equipment and sensors to Valarm Tools Cloud using any GSM cell network, in any country in the world. This is a super useful connector device for Valarm’s Industrial IoT applications, remote monitoring, and sensor telemetry since it’s totally mobile.

Connect a GPS sensor like you see in the photo and you’ve got a cost-effective, reliable tracking device with additional sensor factors like temperature, lighthumidity, fluids, water, or whether switches and assets are on or off. For example, vehicles and trucks used by industrial cleaning companies and chemical cleaning services know where all of their assets are as well as how they’re being used, e.g., how much your company’s vacuums or hydroblasters have been used since their last maintenance routines. See this write-up for more on how to use this GSM sensor hub for cold chain monitoring, trailer + vehicle telemetry, and fleet tracking with integrated Tire Pressure Monitoring Systems (TPMS).

The GSM sensor hubs are also appropriate for stationary Industrial IoT applications like water resources management, chemical distribution, water usage / levels / depths / flow meters, and tank level monitoring. Especially when a cell phone network (e.g., T-Mobile or AT&T in the US) is the easiest way for you to send your Industrial IoT sensor information to Valarm Tools Cloud.

The GSM sensor hub comes in multiple flavors:

These are wireless-enabled modules that connect Industrial IoT sensors to Valarm Tools Cloud through a 3G or 2G GSM cellular network. Each sensor connects to a sensor hub with a Micro B to Micro B USB cable. You can add as many Shield daughter boards as needed to increase total number of sensors you need to connect to each sensor hubSensor hubs / connector devices can be powered either by a USB Micro-B cable and a regular phone charger, or a 5V battery pack.

These GSM sensor hubs have a built-in clock timer feature, which puts the device into a low-power, deep sleep and wakes up automatically at your configurable times. This makes it possible to reduce power consumption to 15uA while sleeping, crucial for applications running on battery or solar panel power. The GSM sensor hub only needs a few seconds to wake up and post data to Valarm Tools Cloud.

The 3G GSM radio module supports the two GSM frequency bands 850 MHz and 1900 MHz used in North-America, Caribbean and Latin America. For a detailed list of frequency bands supported in each country, please refer to the Wikipedia page on GSM Frequency Bands.

The 2G GSM sensor hub uses cellular networks that are 2G / GPRS EDGE, a.k.a. 2.75G. The 2G GSM radio module supports the four most common GSM frequency bands, i.e. 900 MHz and 1800 MHz bands used in Europe, Middle-East, Africa, Asia and the Pacific, and 850 MHz and 1900 MHz bands used in North America, the Caribbean and Latin America. Note: In 2016, 2G GSM networks still have the widest coverage world, however, in some countries the 2G network is starting to be replaced by new technologies with more bandwidth. For example, this is starting to happen with AT&T in the US. Therefore we highly recommend the 3G GSM hub over the 2G / GPRS / EDGE GSM!

The video below shows you in less than 4 minutes how easy it is to connect your sensor hubs to Valarm Tools Cloud.


We’re happy to have this superior replacement for older Valarm Android deployments. These dedicated sensor hubs are much more reliable, readily available, and power / energy efficient.
