There is the greatest demand for electronic weighing scale in vegetable shops, health industries and especially to measure the tiny things. This paper proposes a Wireless electronic weighing scale designed using ultra low power MSP430 controller and with ZigBee wireless communication module. The weighing scale measures the weight with the help of strain sensor and the processor, which has an inbuilt FRAM memory and Real time clock and calendar. This makes the scale to update the weighing databases more accurately and instruction with host PC in a wireless manner. The ZigBee cluster tree network is formed to communicate with more than one electronic scale and the network performance is analyzed using NetSim. The Visual Basic language is developed for user interface in PC side for generating bills.
