Integrated electronic device/system for monitoring rainfall, humidity and/or drought

Current climate changes, including drought, represent one of the most severe and extreme natural phenomena, directly affecting the environment, economy and society, and increasingly leading to soil degradation. In drought-stricken areas, losses in agricultural production are driving up food prices. The world's demand for water will continue to grow further in the coming decades. In view of the presented facts, there is a tremendous need for a systemic approach to saving water in the process of soil reclamation. The problem of fertilization is linked to reasonable irrigation. These processes ought to be synchronized and run simultaneously, under the control by the system. This paper presents a prototype measurement probe as an element of a measurement network.The material complements the article "High-resolution humidity measurements in rational fertilization and irrigation methods as part of soil reclamation under climate change".The project was based on the idea of DIY (do it yourself). This term is associated not only with the independent manufacture of devices - without the participation of professionals and huge financial resources, but also with a non-commercial and free approach - for everyone who would like to use the presented solution. The proprietary prototype of a network of devices for measuring the amount of water and monitoring drought has been designed in a way that guarantees: maximum simplicity, minimum costs, with a short time of execution, maximum repeatability. Each sensor collects nearly 2,000 results in one day. The designed probe, as of today, is equipped with 9 sensors that work continuously, around the clock, sending results every 45 seconds - this gives over 6,300,000 measurements per year for one device working in the network.
