An IoT-Based System to Monitor Soil Parameter of Harumanis Tree

The Internet of Things (IoT) is a paradigm-shifting technology that represents the future communication and computing. The implementation of IoT is widespread and can be used in any industry including the agricultural sector. Mango farming is becoming an increasingly important sector in Malaysia as the country’s population grows. Harumanis mango is the main agriculture in Perlis, Malaysia and is a source of income for the state and local residents. The quality of the fruit produced is inconsistent due to the manual process of fruit and tree monitoring. In addition, incorrect fertilisation and tree care is the main cause of poor fruit quality. Therefore, this project was produced as a system based on the Internet of Things (IoT) to monitor soil parameters of Harumanis trees. IoT systems can reduce labour costs while improving farm management, costs efficiency, crop monitoring, crop quantity, and quality. This system uses a pH level sensor, a temperature, and humidity sensor and a soil moisture sensor to monitor soil conditions of Harumanis farm. The system is a simple IoT architecture where sensors will collect data and transmit it to the cloud database via Wi-Fi. Every data collected during the test is stored in a cloud database using the Blynk IoT platform, which the farmer can use to track the daily growth of the tree from their smartphone or laptop. This system can help farmers in monitoring the growth of Harumanis trees and produce Harumanis mangoes of the best possible quality, and farmers will also be able to react immediately if abnormal data is obtained through the Blynk Application warning system.
