STM32 and DFROBOT TDS METER

im using the DF ROBOT TDS meter for my project using STM32 and lora for communication to mqtt, but the sensor always read 0, im using the analog version for the project

The connection of TDS Sensor with Arduino is fairly simple. Connect the VCC to Arduino 5V & GND to GND. Connect its Analog pin to any analog pin of Arduino. In my case, I used Analog pin A1 of Arduino.

As long as the voltage level is match. As TDS can work between 3.3-5.5V, so they should work together.
