| Abstract: | An intelligent sensor system comprising Freescale MC9S08SH4 and AD7705 is introduced. The hardware circuits and software frame are given. Functions such as software zero adjustment, floating data processing, multi-nodes 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. |
