Abstract

A low-power temperature telemetry system incorporating a miniature micropower temperature sensor/modulator and hand-held decoder with direct digital readout is described. The system is designed to avoid the need to calibrate and characterize individual units while guaranteeing an accuracy of ±0.25°C and a resolution of 0.1°C. The combined sensor and transmitter is constructed using thick-film technology and weighs less than 2.5 g without batteries. Developed principally for wild life tracking and monitoring, the system also has other applications where remote environmental monitoring is required
