IR Thermal Camera Breakout 32x34 MLX90640ESF

DESCRIPTION

The MLX90640ESF is a high-performance, factory-calibrated infrared (IR) thermal sensor array from Melexis. This advanced component transforms your embedded vision system by adding a layer of thermal perception, enabling precise non-contact temperature mapping across a wide field of view.

As a member of the MLX90640 family, the 'ESF' variant features a standard 110° x 75° Field of View (FoV), making it an ideal solution for applications requiring broad area monitoring, from industrial predictive maintenance to smart home automation and scientific instrumentation. Its compact package and digital interface allow for easy integration into a wide range of electronic designs.

FEATURES

• High-Resolution Thermal Imaging: A 32x24 pixel array provides 768 individual simultaneous temperature measurements, delivering a detailed thermal image for accurate hotspot detection and analysis.
• Standard Field of View (FoV): The 110° x 75° FoV is perfect for monitoring larger areas from a closer distance, eliminating the need for complex optical setups.
• High Accuracy & Resolution: Achieves a typical noise equivalent temperature difference (NETD) of <0.1K RMS, ensuring reliable temperature readings even for subtle thermal variations.
• Fully Factory Calibrated: Each sensor is individually calibrated for temperature and emissivity, simplifying development and eliminating the need for complex in-house calibration.
• Digital Interface & On-Chip Signal Processing: Features a simple I²C communication interface with programmable refresh rates (0.5Hz to 64Hz), reducing processing load on the host microcontroller.
• Rugged & Compact Package: Housed in a robust 4-lead TO39 package, the MLX90640ESF is designed for long-term reliability in demanding environments
