HW-691 MLX90614ESF don't work on I2C AB02S

[ibrahimenrique]

Hello there, I got 4 sensors HW-691 MLX90614ESF to test them with the AB02S.

I have been trying some days now to communicate with no success. I am trying in the I2C1, I have tried alreay many sensors in the bus so the bus is working good.

I have not been to get any interaction from the sensor. The sensor have BAA writen in it so the feeding is 3V that is checked. Also I saw the sensor has the pullup resistors so its alone in the bus.

I tried the solution in this post

Doesn't work MLX90614 by SubeCell Board

Hello @sav50. I am also trying to communicate with MLX90614 with no success. I tried the library you mention but it gave me many errors. Did you succeed? Would yoi share your code? Thanks in advance.

But is not working anyway.

It is no even getting the sensor ID usin the I2C_Scan Sketch from the CubeCell-GPS Example files.

Have anyone got some experience with this sensor? I got 4 of them, none is working…

I am using the original wire library coming from the cubecell libray

I appreciate your help.

Thanks in advance,

I have tried the sensors in an Arduino Board and they ar working. I have also been able to run other sensors in the bus with no problem. I also tried with another AB02S and got the same problem…
