Currently, one of the main problems of our time is to improve the ecology of the regions. Green areas can contribute to this, however, the southern region of Russia is caused by a dry summer period. In this regard, there is the task of ensuring high-quality irrigation, which is often carried out by automated systems. However, without feedback, it is extremely difficult to bring the process to the proper level of quality. To do this, use humidity sensors, the price of which inevitably leads to a strong appreciation of the system. This article discusses the possibility and feasibility of developing and implementing its own moisture sensor that would meet such positive criteria as low cost, high accuracy and wide range of measurements, high corrosion resistance, versatility of application.
