THERMOPILE TEMPERATURE SENSOR WITH A REFERENCE SENSOR THEREIN

摘要

A sensor package having a thermopile sensor and a reference thermopile sensor disposed therein. In one or more implementations, the sensor package includes a substrate, a thermopile sensor disposed over the substrate, a reference thermopile sensor disposed over the substrate, and a lid assembly disposed over the thermopile sensor and the reference thermopile sensor. The lid assembly includes a transparent structure that passes electromagnetic radiation occurring in a limited spectrum of wavelengths and an electromagnetic blocker disposed over the lid assembly. The electromagnetic blocker defines an aperture over the thermopile sensor such that at least a portion of the electromagnetic blocker is positioned over the reference thermopile sensor. The electromagnetic blocker is configured to at least substantially block the electromagnetic radiation occurring in a limited spectrum of wavelengths from reaching the reference thermopile sensor.
