For each sensor module,

1. Built-in Temperature compensation and external Humidity compensation available.
2. Another version of sensor module with 5V voltage.

3. We offer full PCB design and manufacturing services.

Description
Based on MEMS gas sensor, the Alcohol EtOH gas sensor module is used to measure ethanol in human exhaled gas. The data is available via I2C or UART series port.
The MEMS gas sensor can be protected by covering a PTFE filter membrane. The sensor module can be assembled by SMT or removable terminal plug connection.

Feature

 BrAC in exhaled gas can be comprehensively and reliably evaluated
 High sensitivity and fastresponse to ethanol gas
 Built-in Temp. compensation and external Humidity compensation available
 Low power consumption
 Small size for convenient installation
 Automatic baseline correction
 The baseline resettable, the storage status settable
 Robust design, excellent long-term stability
 Highly flexible assembly mode and communication interface
