| 520 | |a The intervention of human to the appliances becoming less as the automated system is rising. The key to the automatic devices is the use of a good sensor, transducer, actuator, and excellent control system. Intelligent devices can be described as the device's ability in making the decision with respect to the event that is driven by the changing environment. The current swinging appliances such as stand fan use no controller and sensors for interacting with the environmental condition. This raises the issues of energy wastage and inefficient angle rotation. In this dissertation, research entitles 'novel sensor for human location detection for swing types of electrical appliances' is developed. It outlined two separate sensory systems consist of LV-EZ1 Ultrasonic and D6T-8L-06 Thermal sensors each. Systems can detect the human presence, and estimate its location and direction which allow the swing appliances to direct itself to serve the human. In a situation that we are unable to monitor the device at all time, the device is expected to understand our needs in an intelligent way. It is possible to use two or more Ultrasonic sensors to estimate the location of a subject. However, operating multiples of Ultrasonic sensors at the close range in the same environment and overlapping beam-path introduces interference. This research has overcome the instability of location output due to Ultrasonic interference using Chaining and Average-Smoothing methods. The result shows a noteworthy improvement to the Correct Output Response rate. Subject stays from one meter-left of the Ultrasonic sensor array achieved a 99% Correct Output Rate, recorded a 22% of improvement of sensor reading stability. The second sensor used for detecting human location is Thermal sensor D6T-8L-06 which detecting nothing but heat. This means, human, pets, and all the things that produce heat can be detected too. This similarity of producing heat, however, will always have a significant different due to diversity in properties, physical shape, size, and nature of a subject. The pet's fur act as an excellent insulator to Thermal radiation which difficult to be detected by Thermal sensor. Experiments conducted on cats and human for a non-contact body temperature shows that humans are always giving visible changes in temperature as compared to cat. Even though it can be detected, the changes in temperature value is too small and insignificant. Therefore, the average temperature changes of human is used as a conditional set-point value in the program algorithm to detect any human presence in the room. Upon the human presence, the location is estimated in terms of angle. This angle is then become the current direction of the swing appliances. After conducting a final test to the fans, Thermal sensor system proved to be more accurate in detecting direction and human location compared to Ultrasonic sensory system. Therefore, Thermal sensory system is proposed in this dissertation for cost effective system. | ||
