For this reason, the optimization and improvement of microclimate regulation in warehouses, where vegetables, fruits and grains are stored, is undoubtedly a very promising area of scientific and engineering development. The paper presents a review of advanced scientific and technical literature and new modern articles on the optimization of microclimate control systems on a modern element base. The systems used today were demonstrated, as well as their advantages and disadvantages were analyzed in order to effectively perform the task. The latest research in the field of agricultural industry was analyzed, on the basis of which a list of necessary requirements was created, which would ensure high-quality storage of fruit and vegetable products in storage. In accordance with the requirements of maintaining the indicators of the microclimate, as well as the peculiarities of the preservation of vegetables and fruits, an algorithm for the most effective control of the system of regulating the parameters of the microclimate of warehouses was developed. An advanced element base was demonstrated, which can be used to provide the necessary microclimate indicators, obtain and further analyze the air environment of the warehouse for storage of fruits and vegetables, as well as control devices to control the microclimate indicators. All these steps are necessary to ensure the best indicators of the microclimate of the warehouse, which will keep the raw materials in good condition throughout the shelf life. A printed circuit board, electrical circuit diagram, assembly drawing of the electronic device, as well as design documentation for the device were developed. The technology of PCB creation was analyzed and demonstrated.

The door is an essential part of any structure that provides access and security of lives and properties. The manual operation of a door could be cumbersome and laborious when the traffic volume is high. Also, it has been observed that doors could serve as a medium of spreading the deadly coronavirus disease 2019 (COVID-19) infection. Therefore, a prototype automatic sliding door that plays a crucial role in curbing the spread of this infectious diseases has been designed and implemented in this paper. The design of the prototype sliding door is in two parts namely; the structural part and the automation part. The structural design of the door was achieved using the Microsoft Visio 2016 while the design of the automation system was achieved using express printed circuit board. The implementation of the structural part was achieved using 1 inch particle board while the implementation of the automation system was based on the components like the active infrared sensor, resistors (10 kΩ), capacitor (1000 µF), transistors (TIP41 Q8, BC548 Q7), LED indicators, press button switch, pulley system, drive belt, stepper motor (IP65), and ATMEGA 8 microcontroller. The result of the tests carried out on the door showed that the prototype automatic sliding door was characterized by average opening time, closing time, delay time, and optimal sensing range of 3.10 s, 3.05 s, 5.72 s, and 23.5 cm, respectively. It can therefore be concluded from this work that the prototype automatic sliding door is effective in overriding the manual operation of the door.
