Passive infra-red (PIR) motion detection binary sensors are reasonable for human tracking in household as they can be portable operated by small batteries and be attached onto walls, shelves, floors or ceilings. However, such flexibility of sensor location causes difficulty since the location information of each sensor should be managed and given to the tracking system by the residents. To mitigate...
Embedded devices used in remote network have schedules to transmit analytical data from sensing devices over long distance with long range communication such as General Packet Radio Service (GPRS) with client-server communication. Besides, the existing Master Slave upgrade firmware method requires each connection time for reprogramming. After device installation, firmware reprogramming and reconfiguration...
In this paper, we introduce a new concept design of a Linux-based embedded system for measuring seismic waves. We use a Linux-ready embedded board combined with electronic boards such as an analog-to-digital converter board, GPS, GPRS and a newly designed Common Interface Board (CIB) to create a seismometer in which Linux runs as an operating system. Seismic algorithms, data logging, time synchronization...
Sensor accuracy plays a crucial part in the reliability of sensing applications. Calibration is essentially necessary for accuracy of the sensors. In order to reduce the cost of calibration, it is required that drifting sensors can be identified so that only the detected drifting sensors will be calibrated. This paper presents sensor drift detection by using Adaptive network-based fuzzy inference...
