The system includes a wireless network that combines the functionality of the sensors with the formation and maintenance of the network, while balancing the network with the minimization of the energy consumed by the entire system. The system may include nodes, gateways, coordinators, extension sensors and boosters. The system may perform a method comprising applying a known load to a battery in a first node; measuring a voltage drop in the battery; determining an internal resistance of the battery; estimating a remaining life in the battery based on the internal resistance; and in response to the remaining life being below a remaining life threshold, re-directing, by a first gateway, signals in a mesh network away from the first node and to one or more of a plurality of nodes interfacing with the first node, wherein the first gateway interfaces with the first node and a network.

Energy efficient wireless network of sensors

The system is configured to locate, track and/or analyze activities of living beings in an environment. The system does not require the input of personal biometric data. The sensor system detects infrared (IR) energy from a living being moving in an environment, determines a temperature of the living being based on IR energy data of the IR energy, projects the temperature onto a grid having sequential pixels, determines serial changes of the temperature in the sequential pixels and determines a trajectory of the living being based on the serial changes of the temperature in the sequential pixels.
