MLX90640 32 x 24 Thermal Sensor Module Options

Build a thermal-array display project with an MLX90640 module offering 32 × 24 temperature sensing points.

✅ View a temperature pattern - The 768 sensing points support a thermal image rather than just one spot value.

✅ Choose the viewing angle - BAA and BAB selections provide different fields of view for the intended scene.

✅ Connect to a development workflow - Serial output and an available sensor I2C interface support the described host arrangements.

Match the field of view to the scene

A thermal array lets a project compare temperature patterns across an area. The wide-angle version covers more of a nearby scene, while the narrower version views a smaller area at the same distance.

Check the exact module's power, interface mode and software before connection. Serial data needs a suitable USB-to-TTL path for a computer, and thermal readings depend on the surface and conditions rather than proving a fault or medical diagnosis.
