The Control System of Temperature Acquisition and Wireless Transmission in the Provision Room Based on Single-chip Microcomputer

A wireless data acquisition system is proposed by using RF transceiver chip nRF905,the single-wire digital temperature sensor DS18B20 and the single-chip microcomputer AT89s52.The system consists of a host and several independent slaves,which can achieve collection and transmission of temperature information,display of upper-lower computer and temperature control with temperature ultra-limit alarming.It can be widely applied to the industrial control,data acquisition and other fields.
