Thermopile infrared sensor TPiA 4.4T 4766

Product overview
The TPiA 4.4T 4766 CoolEYE is a compact 4x4 infrared thermopile array providing low-resolution spatial thermal sensing. It integrates a small IR-transmissive lens and a calibrated thermopile ASIC with a digital I2C interface, suitable for cost-sensitive industrial applications requiring temperature detection and basic thermal mapping.

Details
This infrared array sensor delivers 16 pixels (4x4) to enable simplified spatial temperature detection with minimal signal processing. The calibrated ASIC inside a TO39 package provides conditioned outputs and an I2C digital bus for easy integration. Multiple lens options are available to adapt the field of view to application requirements.
