The Wireless System of Data-Acquisition of Temperature Based on Radio Frequency

Abstract

The data-acquisition of temperature is widely used in industrial control, household appliances, medical care, and other important areas often using the data acquisition. For industry, household appliances, and other unsuitable for the traditional wireless data acquisition situation, this paper presents a wireless system of data acquisition of temperature based on radio frequency, and the system can avoid a cable transmission’s the inherent high-cost, long production cycle, the restricted number of transceiver devices such shortcomings . This paper presents the principle, the major flow chart, features system which is mainly made up of MCU ATmega8 and RF chip nF905. Experiments show that this is the accurately and efficiently system of temperature data wireless acquisition and transmission.
