Abstract
A temperature sensing circuit using a thermopile sensor is provided which includes a thermopile sensor generating a voltage corresponding to an incidence amount of infrared rays, means for amplifying the output of the thermopile sensor, means for compensating for an offset of the amplifying means, and means for removing the output of the offset compensating means from the output of the amplifying means, to detect the temperature of an object.
