Data logger with wireless network capability for temperature and relative humidity measurements

Abstract

A data logger for measuring temperature and relative humidity using 1-­wire sensors with wireless network capabilities is described. The system uses the Tiny Internet Interface (TINI^TM) to implement network connectivity for the sensors. Wireless networking is implemented using a Linksys Compact Wireless-­G router. The data gathered by the system is made available to any computer connected to the Internet through a standard web browser. This is accomplished by uploading the information to a public web server. Local computers connected to the wireless network can also directly access the data from the system.
