In this paper, a wireless security monitoring system is developed for the safety of chemistry and chemical laboratories. The remote monitoring and control functions of the laboratory are realized by receiving the information from the laboratory wireless sensor network nodes. The wireless sensor node specially used in chemistry and chemical laboratories is developed to detect fire, toxic gas leak and abnormal sound in the laboratory. Once the insecurity information is detected, the node based on estimated algorithm can control the corresponding implementation of the device, transmit the measuring and control information and images to the handheld terminal at the same time, and give an alarm in order to minimize the laboratory personnel life-threatening and equipment loss. The experimental results show that the developed wireless security monitoring system in this paper can detect the insecurity information of the chemistry and chemical laboratories on-line so that the supervisors can monitor the safety status of the laboratories in time and can take effective protection measures. They can promptly notify the laboratory staff to evacuate quickly, to maximize the protection of laboratory staff safety in emergency. Therefore, the wireless security monitoring system proposed in this paper has a very good practical application value.
