Design of the humiture detection system

This paper designs a humiture detection system which thoroughly complies with the 1-wire protocol. The system comprises of user terminals, relay stations and a neighborhood property management center. The user terminal adopts an integrated linear humidity sensor and a DS2438 temperature sensor to build up the 1-wire protocol humiture sensors, which send real-time humiture data of each room to the relay station via CAN bus. The relay station, in turn, stores the collected data and sends the data to the property management center via the wireless network. The property management center uses LabVIEW, a virtual instrument software, to test the each user´s humiture which can be offset when necessary.
