Design of an Intelligent Sensor System Based on MC9S08EL16

Abstract

An intelligent sensor system based on Freescale MC9S08EL16 is introduced. Hardware circuits and software frame are given. In this system, functions such as software zero adjustment, floating data processing, multi-node measurement and RS-485 intercommunication are added to common sensors. Project practice shows that this intelligent sensor system has many advantages such as high accuracy, compact structure, high reliability and strong anti-jamming ability, etc.
