Description

The emMesh modules in the « em » series are long-range 868/915 MHz radios (up to 16 km*) using Mesh topology to create network availability in places where traditional networks are not available. 

Fully certified, the emMesh module’s very low power draw means it can be powered by solar panels alone, and therefore used even without any electrical grid.

Connected even without a network

Thanks to emMesh technology, your network is built probe by probe through a process called mesh networking. On top of that, with the long range of 16 km between each probe, the emMesh network brings IoT to places that were unreachable until now.

From Mesh to Cloud

Thanks to the emToo communication protocol, the emMesh can be connected directly to an emWay module to reach the emAir online service. Whether for permission management or access to the Google, Apple, IFTTT, Dropbox, Twilio and other APIs, it all becomes child’s play.

Control and access the information collected by your emMesh units from anywhere, whenever you like, with a simple Internet connection.

Sugarbush 4.0

Thanks to emMesh technology, our partner Les Équipements d’Érablière CDL, a leader in the manufacturing and production of maple-syrup equipment, is bringing sugarbushes into the IoT era. emMesh technology makes it possible to control and monitor operations in real time, both in the sugar shack and out in the forest, thanks to its long-range mesh topology. 

With the CDL Monitoring product line, maple producers can monitor yield and many other parameters directly on their computer or mobile phone.
