Temperature-measurement scheme uses IR sensor and sigma-delta ADC


Posted on Apr 3, 2012

Many noncontact temperature-measurement systems use infrared sensors, such as thermopiles, which can detect small amounts of heat radiation. Biomedical thermometers that measure the temperature of an ear or a temple use noncontact temperature measurement, as do automotive-HVAC systems that adjust temperature zones based on the body temperature of passengers. Household appliances and industrial processes can also benefit from the use of noncontact temperature measurement.
