| With the rapid development of wireless communication technology and the increasingly mature of the sensor technology, wireless sensor network has emerged. The emergence of wireless sensor network greatly improve the sensor networks’ and the Internet of Things’ flexibility, and extended there application areas. Meanwhile, it will face new challenges for wireless communication technology. In recent years, wireless sensor network is widely used in the field of medical and health monitoring, environmental monitoring, disaster relief monitoring, smart home, forest fire fighting and even vehicle detection, planetary exploration and so on, it becomes the focus of discussion at internal and abroad.Wireless communication protocol is an important part of wireless sensor network technology. At present, the common wireless communication protocols contain: Bluetooth, WiFi, Zigbee and ANT. Compared with another protocols, ANT protocol has same advantages:ultra-low power, low development costs, flexible networking, and easy-to-use. Therefore, it uses ANT protocol to establish a flexible wireless sensor network.In this paper, it selects the ANT protocol to create the wireless sensor networks through the comparison of several wireless communication protocols. This ANT sensor network is a star network topology, select the ATmegal6L as microprocessor, and nRF24AP2as Radio frequency chip, and achieve the hardware and software of the entire network system. At the end of this article, it achieves the ANT sensor network’s application in the temperature monitoring system. |
