Of course, you can always solder some hookup wire straight to the sensor. It does not measure soil moisture directly (as pure water does not conduct electricity well), instead it measures the ions that are dissolved in the moisture. If you think the video tutorials are essential, please subscribe to our YouTube channel to give us motivation for making the videos. But, if I take the VCC pin and connect it to the 3.3V supply on the RedBoard, the values change. which produces low voltage on signal line. Your interest makes us happy and help to add more projects. ![]() Ebben a projektem sszerakunk egy Arduino s Blynk alap olcs IoT talajnedvessg mrt. ![]() Another option is to solder on a 3-pin 3.5mm Screw Pin Terminal for a slightly more robust connection. ![]() ![]() Water monitoring is very important for a few crops. Get plant watering notifications right on your phone or other mobile device! Indeed the versions of the sensor photographed in this article does not have the voltage regulator at U2 in place (Instead the supply is shorted to Vcc with Zero ohm resistor). initialize the library with the numbers of the interface pins, // These constants won't change.
