Far infrared thermal sensor array (16x12 RES)
MLX90641 MelexisThe MLX90641 is a 16x12 pixel IR array housed in an industry standard 4-lead TO39 package and is able to accurately measure temperatures in the range of -40 °C to +300 °C. The factory-calibrated devices ensure an accuracy of 1 °C in typical measurement conditions. The high accuracy is further supported by a Noise Equivalent Temperature Difference (NETD) of 0.1 K RMS at 4 Hz refresh rate. The refresh rate is programmable in steps from 0.5 to 64 Hz.
Two different field of view (FoV) options are available, a standard 55 ° x 35 ° and a wide angle 110 ° x 75 °. The device is simple to use, operating from a single 3.3 V supply and storing all results in internal RAM for access via an I²C compatible digital interface. A proprietary algorithm ensures high thermal stability, even in conditions where the temperature is changing rapidly. The device's robustness, combined with the extended operating temperature range (-40 °C to +125 °C) enables applications in harsh thermal environments such as cooking, industrial and automotive applications.
