Soil pH Guardian is an innovative system designed to automatically control soil pH levels, addressing the inefficiencies of traditional liming methods. Traditional methods are time-consuming, labor-intensive, and costly due to the need for manual application of lime to each plant. The Soil pH Guardian utilizes components such as soil pH sensors, water pumps, LCD displays, rain sensors, and microcontrollers to automate the process. This system significantly reduces the time and energy required while lowering long-term labor costs. By providing a more efficient and cost-effective solution, the Soil pH Guardian enhances soil management and benefits gardeners and agricultural managers alike.
