Abstract
This paper proposes a wireless multisensory toxic gas detection system. The system allows remote wireless detection of four types of toxic gases, specifically Cl2, CO, NO2, and SO2, using gas detection technologies and wireless communication technologies such as ZigBee and Wi-Fi. Further, we analyze the data collected from sensors to determine a correspondence between the sensors and the gases and establish recognition models for different gases. Through multiple data calibration levels and industrial experiments, we have verified the feasibility of the system, along with its gas detection accuracy and long-term stability.
Highlights
With the rapid development of industrial production in China, unique physical and chemical characteristics of gases have been widely used in the process of chemical production, such as food preservation, frozen food, inflatable packaging, special fuel production, hyperbaric oxygen therapy, and human organ refrigeration [1, 2]
The wide usage of gases will inevitably lead to toxic gas leakage problems [4,5,6]

Summary
With the rapid development of industrial production in China, unique physical and chemical characteristics of gases have been widely used in the process of chemical production, such as food preservation, frozen food, inflatable packaging, special fuel production, hyperbaric oxygen therapy, and human organ refrigeration [1, 2]. The personnel cannot directly enter the site to complete measurement tasks in an actual industrial field having a toxic gas environment, and to ensure safety of the enterprise production and personnel, use of a wireless detection device, if available, will be of great significance [7, 8]. Detection systems with fixed placement cannot accurately detect the exact location of the toxic gas leakage. Improving this accuracy requires multiple terminal equipment, which drives the overall system cost to a much higher level [13]. This paper proposes a multisensory wireless toxic gas detection system based on the actual situation of industrial field. Being able to complete detection tasks in harsh and hazardous environments, the system makes up for the shortcomings of previous detection methods and enables remote wireless intelligent detection of toxic gases [17, 18]
