ABSTRACT
In order to solve the problem of low precision and mobility when collecting the external environment data, be convenient to monitor the external environment, reduce the cost of monitoring external environment, this paper designs a wireless data acquisition system based on the core of wireless transmission module NRF
24L01.
The whole system, in the research project, contains four parts: data acquisition ,single chip controlling ,wireless data transmission and wireless data monitoring . The paper mainly introduces the design and implementation way of hardware and software in each module. By wireless transmission module NRF24L01 to make external environmental data wireless can send the data collected from the machine through wireless module to PC at the site, and do real-time monitoring on the puter developed on the condition of Visual Basic to realize intelligent monitoring to the external environmental data. In practical, the system can deal with the real-time monitoring of external environment, convenient for people to understand. In the meantime, it also has advantages of the simple circuit, the high precision of test data, low power consumption, low cost.
