#207 Why most Arduino Soil Moisture Sensors suck (incl. solution)

Unfortunately, most soil moisture sensors used in our Arduino, ESP8266, or ESP32 projects destroy themselves after a short while. We need a better solution. Today we will test different sensors, and I will show you, how they work and why most sensors from China destroy themselves. And of course, we will find a solution to the problem.
