Abstract

Grain drying environmental parameters are an important issue throughout the paddy grain production process. A real-time monitoring system requires rapid, online, and accurate measurement results. In the paddy grain drying process, the heated air velocity, temperature, relative humidity, and moisture content have to be carefully monitored and maintained to ensure product quality and safety. This study aimed to propose a real-time paddy grain drying and monitoring system using a long-range internet of things (LoRa-IoT). The real-time monitoring system consisted of sensors, LoRa, and IoT platforms. The LoRa end node and gateway were utilized as a wireless radio communication platform of IoT for long-distance signal transmission. From the experiment, the gateway received data from the end node at a distance of 2 km with a time on air (ToA) of 981 ms. As a result, the proposed monitoring system succeeded in measuring and recording the heated air velocity, temperature, and relative humidity data during the paddy grain drying process from 25% moisture content down to 14%. Regarding moisture content, the accuracy of real-time monitoring information was confirmed with a direct measurement method, resulting in a root mean square error (RMSE) of 6.17%.

Abstract

During the dry season, the water evaporation process experiences a significant increase resulting in a rapid decrease in water volume. Conversely, during the rainy season, the open evaporation pan can quickly fill up with rainwater, often causing overflow that disrupts the evaporation measurement process, thus requiring manual intervention to drain or refill the evaporation pan. One proposed solution to address this issue is by implementing an automatic water control system, water temperature monitoring, and water level measurement. The system design consists of two main aspects, namely hardware and software design. Hardware design involves creating a system block diagram and electronic circuit schematic diagrams. Meanwhile, software design includes program and WEB interface design. This research method involves the use of JSN-SR04T ultrasonic sensor, DS18B20 temperature sensor along with ESP32 DevKitC V4 device. Based on the test results, the ultrasonic sensor showed the highest error value of 19.38% with an average error percentage of 4.62% from 55 test runs. Meanwhile, the highest error value on the temperature sensor reached 3.46%, with an average error percentage of 1.46%. Sensor readings, pump status, and solenoid valve status are displayed in real-time on an LCD and Thinger.io dashboard.
