You will need:
1. Sensoterra Single Depth soil moisture sensor
2. MF-400 Gateway
3. Inmarsat IsatData Pro (IDP) Satellite Terminal
4. Sensoterra application software on your mobile phone or laptop
The technical part in simple terms! How does it all work? There are two main networks involved. One is
called LoRaWAN™, and the other is the Inmarsat satellite network.
https://lora-alliance.org
The LoRaWAN™ (‘long range wide area network’) is a low power wireless network that allows you connect
wireless battery operated devices to a gateway that can be several kilometres away. Through this gateway,
the devices can then connect to the Internet. So it is low power, has a good range, and is wireless - these
are the important facts to remember about this network.

The Inmarsat satellite network provides a global, reliable and trusted method of accessing the Internet
using low-powered, portable satellite terminals.
Your Sensoterra single depth sensor sits out in a remote area of your land. Every hour your sensor sends
information to the MF-400 Gateway. This is sent over the LoRaWAN network that we talked about. It passes
the information to the IDP satellite terminal, up to the satellite in the sky, back down to a satellite receiving
station, called the IDP gateway, which then passes it on to the MinFarm Bridge Server, and then on to your
mobile phone where you can view it using the Sensoterra application software. This flow of information can
be seen in Schematic 2, just slightly more detailed than Schematic 1.
