Nowadays, the water is the most valuable natural resource. Not only humans depend on it; cities, industry, agriculture, among others also do. Water is present in different kinds of sources such as rivers, aqueduct, and wells. For example, water wells has been used on multiple applications such as harvest, human consumption, irrigation, and industry since centuries ago. However, monitoring and control the well is an exhausting duty. For instance, monitoring the pH quality is fundamental for the agriculture, food industry, food chain and farmers healthy. On the other hand, with the inclusion of Internet of Things (IoT) in many economical sectors, this paper takes advantage of this approaches to obtain a cheap solution that helps farmers around the World. Our main contributions are design and deploy a low-cost system based on IoT and cloud-based real-time databases which could be used by farmers to reduce and prevent pollute water consumption.
