The CTT Node is an innovation that allows you to automatically localize LifeTag and PowerTags with a high degree of accuracy. For example, nodes can be placed at multiple nesting sites to detect presence or absence.

If deployed in a grid fashion, the nodes can operate as “reverse GPS”, providing near GPS accuracy.

The node uploads received tag detection data to base stations, including the SensorStation, creating a dense, high resolution tracking network. A large, high efficiency solar panel is coupled with an MPPT charge controller, allowing the node to keep its batteries topped off in many different lighting conditions. A high capacity battery also allows the node to be operated for a week without any sunlight.

In addition to reporting detected nearby tags with a precise timestamp, nodes also provide health information. This includes battery voltage and temperature.

Each CTT Node has a detectable range of about 250-300 meters, and is able to relay data to a CTT Base Station as far away as several kilometers. Each solution can be engineered to your needs, or you are welcome to create your own.
