The objective of this study is to develop a smart monitoring and control system for a modified greenhouse dryer for agricultural products utilizing Internet of Things (IoT) technologies and wireless sensor networks. This system enables real-time monitoring of air temperature and humidity, activation of the exhaust fan, adjustment of the heater, and determination of the optimal heating time. The investigation focused on the implementation of a microcontroller in the modified greenhouse system. The system possesses the capability to issue commands for the initiation of the heater and exhaust fan while also facilitating real-time monitoring. The system is equipped with an emergency command that can temporarily halt activities. The system utilizes two different temperature ranges, namely 45°C-50°C and 35°C-65°C, to analyse variations in heater usage across different temperature levels. Both software tools (Telegram and Google Excel spreadsheet) possess the functionality to monitor and regulate the temperature within a greenhouse by utilizing the chat network Telegram. Furthermore, the users possess the capability to store and access data related to the greenhouse system within an Excel spreadsheet. © Published under licence by IOP Publishing Ltd.
