The mouth poison alarm is designed for real-time monitoring of safety hazards in tunnels, underground passages, basements, subways, public places such as sports venues, large businesses, new and old residential areas, kindergartens, parks, hospitals, as well as production units such as laboratories, pesticides, chemicals, semiconductor materials, etc. It uses imported sensors to measure and display the content changes of toxic gases such as sarin, tabun, soman, VX, mustard gas, phosgene, and Lewisite in the space in real time. The internal circuit is designed using a microcontroller, with LED digital display, sound and light alarms, and power supply from the grid. This alarm device has the advantages of long lifespan, good stability, strong anti-interference ability, small size, light weight, and simple and convenient installation. At the same time, it has digital display and sound and light alarm functions, prompting safety warnings within the area and effectively protecting the safety of personnel in enclosed spaces.
