Battery Measurement on Experimental Testbed for Wireless Communication through Xbee

Many Zigbee-based wireless sensor networks have been developed for agriculture monitoring. The main attractiveness of Zigbee wireless technology is in its potential to set up self-organizing network that requires no network backbone and extremely low cost with low-power wireless networking. This paper provides experimental test results on actual voltage measurement using Zigbee protocol devices when communicating temperature, humidity and soil moisture data. The nodes are capable of relaying data up to 143 meters outdoor on unobstructed line of sights with requirement 5% data loss is fulfilled. The results can be used for battery lifetime prediction and suggest the suitability for Zigbee wireless communication for short-range outdoor applications.
