Design of a solar dryer dome type temperature and humidity monitoring system based on IoT (Internet of Things) using LoRa and the ThingSpeak application

Abstract

The application of IoT in systems using the Internet of Things already exists and is starting to be spread, one of which is in the agricultural sector. In this research, a tool was designed to control temperature and humidity using the ThingSpeak application with a standard IoT (Internet of Things) system. Control consists of sending temperature and humidity data from the SHT10 sensor by the LoRa ESP32 IoT (Internet of Things) system to the ThingSpeak application using experimental methods with experiments on the solar Dryer Dome. The ThingSpeak application (SHT10 data receiver) system can unite the Dryer Dome solar room. It will connect to the network to send information in the form of room temperature and humidity conditions to the user via the ThingSpeak application. The results showed significant variations in temperature and humidity throughout the day, with changes influenced by cloudy weather factors. In this study, the highest average temperature and lowest humidity occurred on day 2 at 13.00, with an average temperature of 54.1°C and humidity of 22%. Meanwhile, the lowest temperature and highest humidity occurred on day 3 at 06:00, with an average temperature of 17.8°C and humidity of 92.9%. Monitoring is essential to understand environmental changes affecting agricultural processes, such as using solar dryers to dry agricultural products.
