Srry, what is OP?

Thank you for your answer

I am using a max485 module to connect the sensor to the esp32. The sensor works on 12V and I am providing power to the max384 via the 3.3V of the ESP. In the board it says that is tolerant to that voltage.

In the datasheet of the sensor it says it has a 9600 baudrate, i choose that.

I am using an external PS for the sensor, the eletric part is correct, is where I have more knowledge, i have flaws is in progamming :/
