Wireless weighing Wireless systems typically are battery driven systems. It is essential to have a low current consumption of all the components. The new ZigBee standard introduces an attractive solution for the RF communication. But what about the sensor? Metal strain gages themselves draw 3 mA and more when connected to a 3 V supply. This easily exceeds the acceptable current consumption. | ||||||||||||||||||||
