In order to realize the automation of farming, the alarm system based on CC2530 was designed in this paper. This study used the temperature and humidity sensor SHT10 to collect data. The system reversed the type of data to the integer. The system was based on the CC2530 which is integrated with the ZigBee protocol. To achieve the effect of the automatic alarm, this work set a standard temperature value. When the actual temperature exceeded it, the system called the buzzer automatically and made all the LED lights work. And the value of temperature and humidity after the conversion would be displayed on the LCD screen. The system can complete the control of temperature and humidity in the greenhouse.

This work uses a Wireless Sensor Networks(WSN) module to design the device of driving cars astern. The WSN node integrates MCU CC2430 and MCU C8051F120. CC2430 has 2.4 GHz IEEE 802.15.4 compliant RF transceiver. The device of driving cars astern can play a more important role when CC2430 communicates with C8051F120. This paper shows how to design an device of driving car astern. It should be applied widely.

“…An oxidation film with high hardness and have good abrasion resistance on the aluminium and its alloy are obtained by micro-arc oxidation(MAO) [1][2][3][4].The abrasion resistance of the MAO film is reflected mainly through the dense layer [5].Except for the solution composition and concentration ,the dense layer thickness and hardness are effected by the electric parameters in the process of preparation mainly [6][7] .The widely switching mode of Micro-arc oxidation is the exchange asymmetric pulse now [8]. The negative pulse can influence the growth speed of ceramic layer, and can influence the composition and phase structure of film also [9].In this paper, a ceramic film with a thickness of about 100 um was directly formed on the surface of 2024 aluminum alloy through micro arc oxidation by controlling the negative pulse current .…”

The influence of different negative current density on oxidation film thickness and dense layer thickness was studied. According to the results and experimental phenomenon，the negative current was adjusted steply, and the dense layer with high rates for 70% of micro-arc oxidation film was achieved. EDS and X-ray diffraction were used to analyse the composition and phase structure of the surface layer and the dense layer of oxide film .The friction coefficient and wear of the surface layer and the dense layer of oxide film were measured by wear machine measurement ,and were compared with hard anode oxidation film. The results show that the oxidation film thickness and the dense layer thickness increase with the rising of negative current density.The micro sparks can be avoided out, through adjusting negative current and a high dense layer of MAO film is got .The dense layer of MAO film contains only oxygen and aluminum elements, so it can not be effected by the electrolyte composition .The alpha Al2O3 level of the dense layer is higher than that of the surface layer, and the friction coefficient and abrasion loss of the dense layer is the lowest among the surface layer and hard anode oxidation film.
