A remote weighing system using the ZigBee protocol is provided to allow data transmission to be conducted through wireless communication between a load cell and an indicator unit, by using the ZigBee protocol, thereby quickly displaying overall data values related to the load of a loaded material in a lift or a crane. A ZigBee network load cell(100) detects the load of a loaded material, and loads measured data values on a ZigBee signal to send the ZigBee signal. An indicator unit(200) receives the data values transmitted from the ZigBee network load cell(100) through wireless communication by using the ZigBee protocol, displays data values calculated as the overall physical quantity and the respective data values transmitted from the load cell(100), and gives an alarm by a result signal outputted by comparing a limited load with a preset reference value.
