It is also possible to read the amount of moisture present in the soil (for judging whether the soil is wet or dry) by linking the analog output (AO) of the module, to one analog input (A0) of the ...

It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot form a variable resistor, whose resistance varies depending on soil moisture. This variable resistor is connected in ...

Using an Arduino, a moisture sensor, an LED matrix, and a few other parts, dr.mcc's build monitors the moisture level in a pot of soil and then lets you know when the plant needs water by ...
