Abstract

A temperature detection device includes: first and second temperature sensors that output temperature signals that are signals corresponding to measured temperatures; a signal conversion circuit that respectively converts the temperature signals, which are output from the first and second temperature sensors, into pulse signals having duty ratios or frequencies corresponding thereto; a multiplexer that selectively outputs one of a plurality of the pulse signals converted by the signal conversion circuit; and an offset unit that offsets the temperature signal, which is output from the first temperature sensor of the first and second temperature sensors, to the signal conversion circuit.
