ESP32 and Annoying Soil Moisture Sensor

Hi, Here is the sensor https://www.dfrobot.com/blog-735.html It works perfectly with Arduino boards. With ESP32: I tried, sensor pins, ADC pins, I2C pins (one at a time) without success. /*CALIBRATION CODE ------------------------------- pot 10cm * 4^2 * pi = 500ml +20 30ml 316 +10 40ml 216 +10 50ml...
