This article developed an intelligent anti-virus mask, which is composed of MQ-135 sensor, single-chip microcomputer, valve mechanism and so on. When there is no poisonous gas, the valve of the canister of the mask is opened to breathe normally; when there is poisonous gas, the valve of the canister of the mask is closed and an alarm is issued, and air enters and exits through the canister. Experiments show that the gas mask can accurately detect the concentration of alcohol gas volatilized by alcohol diluents of 30%, 50% and 80% concentration, and trigger the mask to perform alarm and protective actions in a timely and accurate manner. The experiment verifies the safety and versatility of the smart gas mask, indicating that the product has high engineering application value and practical promotion significance.
