Abstracts: Data loggers and data recorders acquire digital data from sensors and other signals. They are primarily used to store data for subsequent downloads to a host PC. In this project we can connect multi sensors to the channel and we can monitor that sensors data when we want. But the advantage is that we can collect data wirelessly in our pc. Zigbee is IEEE 802.15.4 standard which reduces the cost of wire which use to connect sensors but using wireless system it is possible to receive with efficient technique. We can connect more than one zigbee devices by connecting or making network with router and end devices. It is best efficient technique for patient monitoring system in hospitals, and in home security system.
