Wireless telemetry system with self-contained power supply of sensors

A telemetry system based on wireless transmission modules is presented. It consists of several devices connected to radio network. The wireless telemetry system contains three types of devices: a network coordinator, a local radio-transmitting module and a repeater. The local radio-transmitting module (LRM) performs measuring values of signals from sensors attached to it and transmits measurement data over the air to the coordinator. Also the LRM provides self-contained power supply of the sensors. There is a consideration of the local radio-transmitting module in this paper.
