Abstract
A MEMS-based alcohol sensor, comprising a MEMS technology-based alcohol measurement module, an MCU processor (12), a circuit substrate (10), and a housing (30) that covers the circuit substrate (10). The alcohol measurement module outputs a concentration signal to the MCU processor (12) by means of a sampling and amplification circuit module, the MCU processor (12) processes the concentration signal and then outputs an alcohol concentration value. The MEMS technology-based alcohol measurement module and the MCU processor (12) are integrated in the housing (30), so the entire alcohol sensor is small in size, and can be applied to a mobile phone, a wearable device, etc.
