Melexis’ MLX90620 FIRray sensing device uses the company’s noncontact temperature measurement technology to create a cost-effective thermography solution that is suitable in applications such as pedestrian detection, close-range blind-spot detection, and occupancy classification. Covering a -20º to +300°C (-4º to +572°F) temperature range, this element far infrared (FIR) thermopile sensor array produces a map of heat values for the target area in real time, avoiding the need to scan the area with a single point sensor or to use an expensive microbolometer device. According to Melexis, the MLX90620 can simplify the thermal imaging system it is integrated into by immediately capturing 64-pixel images in 2-D, thus keeping the price point in the range needed for high-volume, low-cost applications.
