Abstract

University laboratories store many precisions scientific research instruments and some flammable and explosive experimental materials, and the frequent use of laboratories can easily lead to sudden accidents. While seriously threatening the personal safety of scientific researchers, it also brings huge financial losses to the school. Therefore, how to ensure the safety and reliability of experimental equipment, ensure the safe storage of hazardous materials, and eliminate potential safety hazards to individuals and property as much as possible has become a social concern. Through the use of temperature and humidity sensors, illumination sensors, flame sensors, gas sensors, human body infrared sensors and other sensing devices to monitor the laboratory environment. The gateway composed of ZigBee module and WiFi module is used to complete the data transmission between the terminal and the upper application. Combined with the data receiving and processing capabilities of OneNET Internet of Things open platform, the environmental monitoring function of the whole system is realized.
