This document discusses different types of sensors used for temperature monitoring including resistance thermometers, thermistors, thermocouples, and infrared radiation thermometers. It also shows images of sensor functions for telemonitoring systems, an example of a fire detected using such a system, and the layout of a goaf temperature monitoring system.
