Thermopiles are IR temperature sensors that adopt the same principles as thermocouples. Higher output, faster response time and lower prices have been achieved by making full use of SEMITEC original silicon-micromachining technology based on semiconductor processing. Furthermore, with the use of an additional high precision thermistor for compensation, temperature sensing accuracy has been substantially increased.

SEMITEC'S thermopiles are fully compliant with RoHS DIRECTIVE2011/65/EU.
