We have grouped our thermopiles and pyrodetectors as above by application and type, and have uploaded a few application notes below.


Excelitas has recently launched CaliPile™ - a new range of intelligent compact IR sensors capable of multiple sensing applications. This series of sensors include a highly sensitive thermopile detector and onboard electronics that allow the sensors to be set into three distinct function modes - motion sensing, presence detection and temperature measurement. Form factors include compact SMD housing and traditional TO metal case versions with either aperture window or IR focusing lens.

Applications for the CaliPile Series include short-range presence detection with no additional lens requirements, non-contact temperature measurement and overheating protection, IoT and smart-home products, lighting and printer sensing, and general industry thermal IR detection.

CaliPile TPiS 1S 1385 - ultra-compact SMD housing, requiring only three meters to achieve an effective range for human presence detection, with no additional lens requirement.

CaliPile TPis 1T 1086 L5.5 - TO housing version of the CaliPile IR Sensor Series.

CaliPile TPiS 1T 1084 - robust TO housing and an IR window.
