Mlx 90640 not working

Post by Engku79 »

I just bought and mlx90640 sensor and i connected it to an Arduino due
My connections are as follows
Arduino mlx90630
Scl. Scl
Sda. Sda
5v. Vin
Gnd. Gnd

Ive soldered the connections run the simple test code
When i open the serial monitor it says
Mlx90640 no found
Sometimes it found it but when reading pixels it says "failed" continuosly
What is happening and what can i do to fix this?

There May be an issue with your connections or the wiring of the sensor to the Arduino.

Double-check the connections and make sure they are secure and properly aligned.
Make sure that you are using the correct pins on the Arduino for SDA and SCL.
Check the continuities of your jumper wires.
Confirm that the sensor is working properly by checking its output with a multimeter.
Verify that the I2C address of the sensor is correct and matches the one specified in the test code.
Check if the sensor has any issues with it by testing it with another Arduino or other known working code.
Make sure that you are using the correct library for the MLX90640 sensor and that it is up to date.

Please post a photo of your setup showing how everything is connected.

Is the DUE your only Arduino board?
