Soil moisture is basically the content of water present in the soil. This can be measured using a soil moisture sensor which consists of two conducting probes that act as a probe. It can measure the moisture content in the soil based on the change in resistance between the two conducting plates. The resistance between the two conducting plates varies in an inverse manner with the amount of moisture present in the soil.
User can set low trigger level & high trigger level. Arduino measure soil moisture, if soil moisture is below low trigger level then then water pump will start to increase soil moisture, after that if soil moisture increased & greater then high trigger level then pump will automatic off. These all operation’s are visible on LCD.
Project customization is also available.
