The MLX90614 is an infrared thermometer for noncontact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO39 can. Integrated into the MLX90614 are a low noise amplifier, 17bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the ...
The HTPA16x16d is a low cost thermopile infrared array with 16x16 pixels inside a TO39 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.
