Dallas DS18B20 with FMC130

There is wrong temperature indication - about 300 degrees of celsius. Sensor reacts to temperature changes normally. But something is wrong with sensor data interpretation. Also we tried to use 4,7kΩ resistor between Pin 10 and pin 11, with no success.

Any idea how to fix it? Thanks.

Hello @km.it,

I hope you are doing well. It seems you are receiving an error code from the device related to the Sensor is not properly connected with FMC130. (see screenshot below)

Suggesting you to check on Wiring connection of Dallas Sensor with FMC130.

Kind regards,

Hallo Patrick_Sangalang.

Actually I am not receiving error code. Indicated temperature is about 300 degrees (not 3000).

It seems like a ecoding problem. Even if I devide indicated valued by 16, still the result is not correct.

Hello @km.it,

Kindly note that there is a Multiplier of 0.1 if you are checking the data received from your platform. Otherwise, I recommend you to test another Dallas Temperature to check where the issue comes from.

Best regards,
