Environmental Information Collection System Based on ZigBee and Raspberry Pi

In IoT applications,accurate and reliable environmental information is an important factor in the system to make cor-rect judgments and controls. In this paper,an intelligent environment information collection system is designed. The ZigBee node mounted on the mobile carrier is used to collect information such as temperature and humidity. After passing through the ZigBee router and coordinator,the information is transmitted to the gateway device implemented by the Raspberry Pi. The gateway uses WiFi technol-ogy to communicate with the host computer,and the host computer software is written in C#. The upper computer has functions such as real-time refresh display of the collected information,statistical display of historical data,and issuing commands to the actuator ac-cording to the analysis result of the data. The actuator can perform the corresponding action according to the received command. The ex-perimental results show that the system has lower power consumption and stronger self-organizing network capability than the system with single communication technology.
