Data gateways collect data from the data loggers

Data gateways are devices connected to the Internet and when any of our data loggers are in proximity of our gateway devices, they connect with each other using Bluetooth Low Energy (BLE) and the data loggers then send the data to the servers. The data then becomes available on a Web portal for further analytics, reporting and actionable tasks.

WiFi
Our control units are devices that connect with our data loggers in the field and serve as a gateway to transfer all the data from the devices to the servers for processing. The gateway device is easy to configure using your WiFi network and you can put as many gateways as you need to cover your area. Typically the range of Bluetooth BLE to communicate with our data logger devices is about 50m but since walls and other factors can affect the range, we suggest testing your range and adding more gateways if many rooms must be covered.

GSM (SIM card)
Sometimes there is no WiFi network available. It needs an alternative way to connect to the Internet. Using a GSM SIM card becomes a convenient way to be conneced on the go, no matter where the gateway device is, as long as within the range of a cell tower.

Extend range with a Mesh
A mesh network (also called meshnet) is a setup in which each gateway devices connect directly, dynamically, and non-hierarchically, to other gateways and cooperate with one another to efficiently relay data until it find a gateway that has an Internet connection and is able to send the data to the server.

This lack of dependency on one gateway device allows for every gateway to participate in the relay of information. Mesh networks dynamically self-organize and self-configure hich enables a dynamic distribution of workloads, particularly in the event a few nodes should fail.

Data Gateway (Solar Panel)

The gateway devices need power to operate. In outdoor scenarios, there might now be any power source available (e.g. in a field or a vineyard).Our gateway devices can be connected to solar panels to operate, making it a highly flexible solution for outdoor and remote projects, where power srouces are hard to reach.
