Introduction to the Tinytag Radio System

The system is easy to set-up: it consists of a receiver connected to a computer or LAN and a number of radio loggers which self-configure to form a robust mesh network.

Radio loggers work together to send information to the receiver. They are able to receive, log, store and transmit data. If a logger is out of range and cannot send the data directly to the receiver, it will re-route it via other loggers. If a logger has lost all connections and is unable to find a way of sending the data to the receiver, it stores it locally until communications are restored. Alarm warnings can be sent via email or SMS enabling corrective action to be initiated.
