Abstract. Under the background of big data and cloud computing, in order to design a kind of agricultural data collection and communication system, MSP430 is taken as core controller and processor. DS18B20 as temperature acquisition, DHT11 sensor as humidity data acquisition, BH1750FV1 as light sensor. The collected data will be transmitted through the wireless communication module, and communication with the host computer. The design of the system is divided into hardware design and software design. This system can extend to join the ZigBee or BeiDou communication module, which can be applied to the large-scale intelligent agricultural control. Keywords: Agricultural data acquisition humidity sensor Wireless communication

1 Introduction At present, China’s agricultural production efficiency is not high mechanization and information technology is also not high. Due to various reasons, farmland is not easy to management directly [1]. With the development of the Internet of things (IoT), the IoT technology will quickly penetrate into every link of agriculture. Temperature, humidity, light intensity and other data are important environmental parameters in agricultural production, especially in greenhouse cultivation, aquaculture and other precision agriculture. They are essential for agricultural production, these parameter will directly affect the quality of agricultural production and agricultural production, especially in the environment changes, if not check and control timely, agricultural production will cause serious damage [2]. In many agricultural and even industrial applications, the measurement of process, production and environmental parameters is still a real time monitoring. The purpose of this design is to study the distributed node control and © Springer Science+Business Media Singapore 2015 X. Zhang et al. (Eds.): ESTC 2015, CCIS 572, pp. 77–86, 2015.

communication program, to further promote, it can be suitable for large-scale information agriculture.
2 Overall System Architecture The wireless data acquisition and communication system including three parts, the first part is the universal application of DS18B20 as the core of the temperature measurement module, the digital sensor DHT11 as the core of the humidity measurement. BH1750FV1 is used for light intensity. In this system, NRF24L01 is selected for the wireless transceiver module. The microcontroller is MSP430, it is mainly responsible for real-time data display, and it can communicate with PC through the USB interface, which can achieve real-time monitoring of temperature, light intensity, humidity and
