For a wide range of applications in industry, it is sometimes necessary to perform acoustic source localization. In this paper, a passive sound localization and classification system is designed and implemented. Each sensor consists of a microphone array which is used to detect the direction-of-arrival (DoA) of an acoustic signal. Multiple DoA sensors can be combined to form a wireless sensor network...
Fish conservation is a concern due to the impact of industrial fishing that causes overfishing. Fish farming has been an approach to fish conservation and systems are required to monitor ecosystems. This paper describes the design of a solar powered autonomous fish pond management system that can be used for fish conservation. The system consists of a floating node, equipped with sensors, that is...
Biometric systems are important for access control and authentication in various application scenarios. Single biometrics can be selected for authentication, but a multimodal approach is typically more reliable. In this paper, a multimodal biometric authentication system is developed. It consists of wireless sensor nodes equipped with accelerometers and infrared cameras, which enable analysis of gait...
Hazardous environments at the workplace are a significant contributor to injuries due to accidents as well as chronic diseases. There are many occupational health and safety (OHS) systems, but they are costly or not flexible. This paper presents a low-cost OHS. It consists of various sensors that can be used to monitor whether a safety helmet is being worn, the worker is mobile and safety boots are...
In emergency situations such as fires in homes and offices, it is often the case where members of a response team (eg. firefighters) are not able to locate each other due to fire and smoke. It is desirable to have a system which is able to locate all personnel such that a team leader can monitor their location and to enable the firefighters themselves to know their proximity to other firefighters...
There is a persistent problem that continues to be a relevant demand for the chemical, oil, food and pharmaceutical industries, the fouling detection in ducts systems. This work shows the early tests to develop a platform for detecting fouling in pipes and analyze specific locations using the impact hammer test based on a wireless sensor network communication. To minimize the costs of maintaining...
With the world progressively heading towards an energy crisis, renewable energy sources and technologies have become the focus of research. Harvesting the sun's energy through solar thermal power plants (STPPs) is an attractive alternative to the use of energy supplied through the grid. However, installation and maintenance of cabling for communication and control of a heliostat array for STPPs is...
A wireless sensor node platform was created along with a base station that can be used to monitor various parameters in the industry. A literature survey was conducted on important parameters found in the industry. The various standards that are set out for these parameters were analysed. The developed wireless sensor node platform along with the base station shows that a wide variety of industrial...
Water is a vital component in our daily lives, and a precious resource to human race. This paper describes the work carried out on the design of a water management system that can log pressure and pH readings wirelessly and determine if there is a water leak within the pipe system or if the pH levels of the water are safe enough for human consumption. A pipe monitoring system was designed, implemented...
