Air blowing method-based alcohol sensor, and smart device

Abstract

An air blowing method-based alcohol sensor and a smart device. The alcohol sensor comprises an alcohol measurement module, an air pressure measurement module, an MCU processor, a circuit substrate, and a housing coveringly arranged on the circuit substrate; the alcohol measurement module transmits a concentration signal thereof to the MCU processor by means of a sampling and amplification circuit module, the air pressure measurement module and the MCU processor are mutually connected and implement transmission of an air pressure signal, and the MCU processor, after performing processing on the concentration signal and the air pressure signal, outputs an alcohol concentration value. The alcohol measurement module and the air pressure measurement module are integrated within the housing.
