If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a ... I love all about electronics, circuit diagrams and crazy projects that can help us achieve almost ...

These probes act as sensor elements that register moisture and change it into an electric value. This value is further processed into information in the form of an electronic display. Fig. 2: Circuit ...

In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how ...

If the moisture value is above 1000, LCD displays “Sensor is not in the soil”. Make connections as per the circuit diagram. Connect Nano Cable with Computer. Connect Vcc of the sensor to 5V and ground ...
