Soil Moisture Sensor Module

Soil moisture sensor measures the water content in the soil. Measuring soil moisture is important in agriculture to help farmers manage their irrigation systems more efficiently. Not only are farmers able to generally use less water to grow a crop, but they are also able to increase yields and the quality of the crop by better management of soil moisture during critical plant growth stages. Besides agriculture, there are many other disciplines using soil moisture sensors. Golf courses are now using sensors to increase the efficiencies of their irrigation systems to prevent overwatering and leaching of fertilizers and other chemicals offsite. The module uses the LM393 comparator to compare the soil moisture level with the preset threshold. When the soil moisture deficit module outputs a high level and vice versa.
