Implementation of IoT Sensored Data Integrity for Irrigation in Precision Agriculture Using Blockchain Ethereum

Nowadays IoT is one of leading technology in industrial era 4.0 which has been implemented in various sectors such as agriculture. IoT is commonly used to transmit sensing data which is then stored in the database. When IoT network is large, the more data is stored. Furthermore, it causes various problems including data security and data integrity issues. In addition, Blockchain Technology is a decentralized system which all nodes in the blockchain network stores a copy of the recorded information. To overcome this problem, this study proposes the implementation of blockchain in IoT sensor data to reduce problems such as data manipulation. Real time irrigation data sensor is used for this research. Experimental result shows that Ethereum-based blockchain with using consensus proof-of-work as a blockchain network is able to ensure integrity of irrigation data sensor.
