Description
This specific IR Array Breakout features a 55°x35° field of view with a temperature measurement range of -40°C-300°C. The MLX90640 IR Array has pull up resistors attached to the I2C bus; both can be removed by cutting the traces on the corresponding jumpers on the back of the board. Please be aware that the MLX90640 requires complex calculations by the host platform so a regular Arduino Uno (or equivalent) doesn't have enough RAM or flash to complete the complex computations required to turn the raw pixel data into temperature data. You will need a microcontroller with 20,000 bytes or more of RAM. To achieve this, we recommend a Teensy 3.1 or above.
Note: The I2C address of the MLX90640 is 0x33 and is hardware defined. A multiplexer/Mux is required to communicate to multiple MLX90640 sensors on a single bus. If you need to use more than one MLX90640 sensor consider using the Qwiic Mux Breakout.
