Development of a practical mechanism for the environmental direction of the “Green Office” programme when watering indoor plants in accordance with sustainable development

The object of research is a continuous action device with an alarm for rationalizing the irrigation system, which will help support the sustainable development program and improve the environmental situation in the country. The problem solved in this study is related to the need to optimize the consumption of resources during plant care at enterprises of various forms of ownership that have begun to introduce environmental management. This is also one of the problematic aspects associated with the landscaping of industrial centers, offices and premises where a significant number of people work and live. The development of mechanisms for solving the problem should contribute to increasing the decorative properties of plants and optimizing work related to care, watering and maintaining a given soil moisture. In order to solve the problem, a simple-to-use device for maintaining optimal soil moisture in pots (containers) with indoor plants has been developed, which occurs by visual registration (when the LED lights up). This is due to the fact that the order of mounting and arrangement of needle electrodes in the design of the plant container with the placement of the LED on the soil surface has been changed. The proposed design features have made it possible to constantly monitor soil moisture – if the humidity reaches a value less than the required value, the LED turns on and records the need for watering. Thanks to the conducted research, an increase in the qualitative component of moisture intake is ensured, the decorativeness of plants increases and the risk of their death is reduced, which will allow enterprises to actively move towards supporting the “green” economy. Compared with known analogues, the device gives confidence in the reliability of soil moisture control in containers with plants, and in case of its deviation from the optimal indicator, the sensor gives an instant light signal. The proposed development also allows to improve the qualitative composition of the moisture supply, optimize the use of water resources, reduce death and increase the efficiency of plant care while ensuring their healthy growth.
