Product Options


The A753 addWAVE is a universal measuring, logging and radio telemetry unit designed for year round unattended operation. This solar powered, lithium or mains powered unit is designed for use in almost all environments and allows the collection and transmission of a multitude of parameters from large scale networks.

The 500mW output radio telemetry unit transmits in the 70cm frequency band between 430 and 470MHZ. It can achieve transmission distances of up to 20km. This enables distances between remote locations and base station to be extended and can also enable successful radio transmission over difficult terrain. No external enclosure is necessary as all components (power supply, data logger and radio) are contained in one compact aluminium enclosure that has an IP67 rating. Installation is as simple as connecting the enclosure to a mounting post, to the sensors and to a solar panel, with no other know-how required.

By default the A753 addWAVE supplies power to the sensors that are attached to it (up to 52 with 4 digital inputs and 4 digital outputs as well!). For this reason it is necessary to pay particular attention to the power consumption of the sensors that are to be used. For advice on the most suitable sensors to use with this RTU please contact us.
