Low Power Strain Gage Measurement with Wireless Network Access

Abstract

This paper describes a measurement system for industry applications where the weight has to be monitored in a flexible way. The measurement system can be used to build several kinds of weight cell applications in which the low power sensor is battery powered and able to communicate with a master unit through a wireless network. The system requirements are described and all blocks derived from these requirements are presented. The implementation of the wireless network includes a peer-to-peer connection between multiple measurement units with the master unit by using just one communication channel.
