Description

This simple plant watering system uses the Soil Moisture Sensor to estimate the moisture level of soil and display it on the LED matrix screen. An optimum moisture level can be calibrated and using Water Pump you can then maintain that level. Sensor works by measuring a voltage related to the conductance of the soil and using it to estimate the amount of moisture in the soil.
