The amount of moisture in the air is represented by relative humidity (RH); an ideal level interior environment between 40% and 60% at temperatures 18° 20° Celsius. When RH falls below this level, becomes dry, which can cause skin dryness, irritation, discomfort low temperatures. rises above 60%, a wet atmosphere develops, encourages growth mold mites. Asthma allergy symptoms may occur as resul...

This article describes a system for measuring temperature by monitoring an object’s radiation in the infrared spectrum. Using a measuring device by passing through a data acquisition interface, a long-term observation of the temperature variance of objects on a personal computer by the LabVIEW software is conducted. A special mechanism joined with a pyroelectric infrared ~PIR! sensor, optical c...

This paper presents a new approach to monitor an indoor environment on thermodynamic basis. It uses temperature as the driving parameter and is especially suited for comfort analysis or evaluation of moisture. The method is based on infrared (IR) thermography, which proved to be very effective in this application. The system measures all fundamental environment parameters (e.g., air temperature...

Recent advancements in depth video sensors technologies have made human activity recognition (HAR) realizable for elderly monitoring applications. Although conventional HAR utilizes RGB video sensors, HAR could be greatly improved with depth video sensors which produce depth or distance information. In this paper, a depth-based life logging HAR system is designed to recognize the daily activiti...

Recently, indoor air quality monitoring (AQM) has become an important research area for the concern of human health and lifestyle. The AQM is usually based on the deployment of wireless sensor networks (WSN) within the building. Bridging the gap between gas sensors, deployed at different locations of the WSN, and the Internet becomes a challenging task in terms of link reliability and data inte...
