The research of environmental monitor system in brewage house of alcohol factory based on WSN

The paper presents a wireless sensor network system, including 433 MHz, ZigBee wireless network, data collection node and data concentrator node. This system is mainly to apply to monitoring winery´s environment, the principle of which is that data collection node uses 433 MHz wireless network to send data, data concentrator node uses 433 MHz wireless network to receive the data from data collection node, then sends the data to the sever by ZigBee module through the processing of MCU. Meanwhile the personal can examine this data to monitor the change of winery´s environment. The practice proves the function of WSN system and guarantees the quality of liquor-making.
