Developing hardware and software complex for remote control of greenhouse microclimate

The development of Internet technologies allows remote control of various devices. The paper presents a description of a greenhouse microclimate control device with remote control. There are used the concept of the Internet of Things, which allows to remotely control devices using cloud services. The Internet of Things is one of the popular trends in the networking environment allowing data to be transferred between devices. There is no need to write a program to transfer data, it is enough to use one of the many existing cloud services. The cloud service records the microclimate parameters and displays them on-line on the user's computer or phone. The user can observe the data received from the sensors installed in the greenhouse and control the executive devices, namely, turn on and off the heating, irrigation, lighting and opening of the vents. The device under development will help not only take the microclimate indicators in the room and transfer them via the Internet to a personal computer or telephone while being remote from the measurement object, but also control the actuators inside the greenhouse. The functional requirements for the developed device are determined, the block diagram of the device is shown, the main element of which is the Arduino Uno board, on which not only the microcontroller is located, but also the connectors of external devices. The user interface is presented and described, which provides interaction between a user and a control object, developed in the IoControl cloud service, and the stages of its development are also presented. The modes of microclimate control and the corresponding actuators and variables are considered.
