Far infrared thermal sensor array (32x24 RES) - MLX90640
Product description
Addresses growing demands seen across numerous applications for thermal analysis. This infrared (IR) sensor offers a cost-effective alternative to more expensive high-end thermal cameras.
This 32x24 pixel device is suited to safety and convenience applications that include fire prevention systems, smart buildings, intelligent lighting, IP/surveillance cameras, HVAC equipment and vehicle seat occupancy detection.
It has a -40°C to 85°C operational temperature range and can measure object temperatures between -40°C and 300°C. Maintaining high levels of precision across its full measurement scale, this infrared sensor delivers a typical target object temperature accuracy of ±1°C. It also exhibits superior noise performance.
Unlike microbolometer alternatives, the sensor does not need frequent re-calibration, thus ensuring continuous monitoring and lowering system cost. The Melexis MLX90640 is supplied in a compact, 4-pin TO39 package incorporating the requisite optics. An I²C-compatible digital interface simplifies integration.
