16x16 Thermopile Infrared Array

The HTPA16x16d is a low cost thermopile infrared array with 16x16 pixels inside a TO-39 metal housing. This is a low cost alternative for the HTPA32x32d and can be used for thermal imaging, person detection and presence detection.
Due to the digital I²C interface, only four pins are needed for operation. The integrated 16-bit ADC has a high resolution and the built-in EEPROM can store all calibration data. The HTPA16x16d can be operated with framerates between 40 Hz and 70 Hz depending on the chosen ADC resolution. Different optical lenses are available, and the field of view can range between 45 degrees to almost 90 degrees.
For applications like person detection, for which no exact temperature value is required, the detection is based on contrast between target and background, and the array can be delivered without factory calibration at lower cost.
