32×32 Thermopile Infrared Array


32×32 Thermopile Infrared Array

The HTPA32x32d is our high performance, high quality, digital signal thermopile infrared array with 32×32 pixels inside a TO-39 metal housing. With the integrated optical lens, fields of view from 33° to 105° can be achieved. This makes the HTPA32x32d a perfect fit for person detection in smart building applications. Due to the digital I²C interface, only four pins are needed for operation. The built-in EEPROM stores calibration data, and the integrated ADC has 16-bit resolution. Framerates of 15 Hz to 27 Hz result, depending on the chosen ADC resolution. True shutterless and uncooled operation of the thermopile array ensures very low power consumption with a high performance.
