This parts is now obsolete (May 2021), an alternative part is the new SMT IR2102.

The Smartec infrared sensor SMT IR9902 is a sophisticated full silicon infrared sensor with built in temperature sensor (Ni). This sensor can be used for measuring non contact radiation temperature. The sensor is fitted with a 5.5 µm high pass filter. For different radiation temperature ranges other filters are available. These sensors output a small analogue voltage. An amplifier and interface is required before the voltage can be digitised and referenced to the temperature.

* Overall accuracy and sensitivity
* High pass IR filter (>5.5µm)
* Fast 40mS response
* Analogue output
* Applications: Climate control, Medical, Temp control of moving objects
