Abstract
The Internet of Things is a network of smart sensors that can control and monitor things from anywhere over the Internet. This smart system can be used to improve the productivity and quality of modern farming. Therefore, the present research aimed to propose a smart farming application powered by the Internet of Things. In this research, the prototype of a smart capsule was developed to measure the humidity in paddy bags stored in various locations within a warehouse. This smart capsule used Node MCU ESP8266 microcontroller and the SHT21 humidity sensor to send data to the Blynk server over a Wi-Fi network. Arduino IDE was used to write a C++ code for the microcontroller. The Blynk mobile application was used to monitor and display real-time humidity data through the digital dashboard. The collected humidity data were further analyzed and used to develop a paddy storage system for the future. In addition, when the smart capsule lost contact with the Blynk server, a notification was sent to responsible persons in a timely manner. The research results indicated that the developed smart capsules and Blynk application can effectively work together and are deemed suitable for use in smart farming.
