The module is already commissioning, calibration of the completion of the "bad breath detector," the core components, users will be its use as a standard electronic components;
Using HIG series of 8-bit MCU (12bit A / D) control system, sensor for the SM series MEMS (C₂H₅OH) gas sensor;
Wide operating voltage range, the user can be easily applied to different systems;
The user can configure the application software at different bad breath of alarm points;
Can be used alone alarm buzzer
