TMP007 Infrared Thermopile Sensor

Texas Instruments' IR thermopile sensor with integrated math engine in chip-scale package

Image of Texas Instruments' TMP007 Infrared Thermopile SensorTexas Instruments' TMP007 is an infrared (IR) thermopile sensor that measures the temperature of an object without contacting the object. The integrated thermopile absorbs the infrared energy emitted from the object in the sensor field of view. The thermopile voltage is digitized and provided as an input to the integrated math engine, along with the die temperature (TDIE). The math engine then computes the corresponding object temperature.

Default calibration and thermal transient coefficients are stored in the built-in nonvolatile EPROM memory. Application-specific values can be stored for improved accuracy. An alert function is available, and can be programmed in either comparator or interrupt mode.
