Soil sensors are instruments monitor soil moisture conditions. They can be categorized into sensors that monitor moisture, conductivity, temperature, nutrients, pH, and salinity. All these different types of instruments are collectively referred to as soil sensors. With advancements in technology, there are now more advanced soil sensors available that can simultaneously measure soil moisture, temperature, Conductivity, and nutrient content.In the process of agricultural cultivation, it is essential to have a timely understanding of the soil condition in order to determine which types of crops to plant based on the soil situation. This includes knowing when to replenish soil moisture and when to fertilize and apply specific types of fertilizers. By doing so, it becomes possible to effectively improve crop yield per acre and increase agricultural income.
