The Internet of Things (IoT) is widely used in various aspects such as industry, manufacturing, health, agriculture and others. One of the uses of IoT is as an environmental monitoring system. In its application, IoT-based environmental monitoring systems are composed of one or more sensors placed in various locations and connected to each other using certain protocols. The problem arises when thousands of IoT devices connected together in one network and using the server-client connection model which raises several works in the synchronization process and access control management. This kind of network depends on a server as the center of control management that work as storing and distributing data from the sensor so that any data comes from the server is considered correct. To overcome this problem, it is proposed an IoT system that uses Blockchain technology which is a distributed data structure that forms blocks that do not require central authority and verification from third parties. From the experiments conducted can be evaluated that blockchain communication is much slower compared to MQTT communication protocol in terms of speed. The data transmission between node is measured with an average delay of 200ms. This system also visualizes data in graph with a high mobility data collection using vehicle so that it can be used to be an alternative of public participatorial measurement.
