Gemini Data Loggers (UK)
This Tinytag wireless data logging system consists of a receiver which is connected to a PC and a number of radio loggers. Each radio logger is a self-contained, battery powered unit that can receive, log, store and transmit data to other radio loggers, as well as the central receiver.
Each radio logger has a line of sight range of up to 100 metres, but there is no limit to the number of loggers you can have, or to how far away you have them. Data will always find its way back to the PC because it can be relayed from one logger to another logger in range, until it finds its way back to the receiver. The loggers will dynamically adjust to deal with obstructions. If a logger is unable to find a path back to the receiver, its data is stored locally until such time as a path becomes available.
This combination of features delivers a very robust radio network which ensures that data is never lost during transmission. The radio software provides mechanisms for third party integration using Modbus or http accessible CSV files. This software is also fully compatible with 'wired' Tinytag products and existing users will find the interface familiar. Data from the receiver can be accessed over a network.
