Design and Implementation of a Low-cost IoT Node for Data Processing, Case Study: Smart Agriculture​

The majority of IoT nodes work within specific scenarios and can be configured in different ways. This paper seeks to design and implement a low-cost Internet of Things node for research applications to make it suitable for a wider variety of scenarios. The design is divided into hardware board and mobile application. With Bluetooth, the mobile application can connect to the node, and the node can collect data, store this data in the ThingSpeak database, control some connected devices, and check if the connected devices are on or off. The node was designed and tested for research purposes using smart agriculture as the case study. The system detects temperature, humidity, and soil moisture using node sensors, enabling data collection and interpretation by smartphone and web application. There are many challenges associated with the collected data preparation, analysis, visualization, and prediction using the Softmax function for optimal future management. Python was utilized to apply necessary data analysis techniques. The system saves time and makes farming more convenient as it uses few resources in terms of hardware and cost.

ThingsDriver: A Unified Interoperable Driver for IoT Nodes​

The Internet of Things (IoT) is one of the fastest-growing technologies in recent years. However, many IoT service providers design their IoT solutions with non-interoperable hard-ware, scenario-specific features, and unique architectures that make these deployments fragmented rather than collaborative. Collaborative IoT (C-IoT) systems are considered the natural evolution of the traditional IoT. Sharing the infrastructure is one of the main concepts that C-IoT depends on to create a collaborative environment between different applications. With the current fragmented IoT, these applications cannot share their infrastructure and data due to the lack of standards to organize the C-IoT space. In this paper, we introduced Unified Interoperable Driver for IoT (UIDI) nodes. UIDI uses a novel programming methodology that enables node interpreters to provide general-purpose firmware for IoT nodes. UIDI allows the users to configure IoT nodes according to their usage, preferences, and needs through the cloud. We developed a proof-of-concept prototype to demonstrate the feasibility and usability of the proposed UIDI using NodeMCU and Arduino-Uno. The performance of UIDI outperforms Firmata by 27%. In addition to that, the UIDI platform is a standalone node that connects directly to the cloud, whereas the Firmata node requires a host to be accessible from the cloud.
