FEATURES
-
The module is already commissioning, calibration of the completion of the "breath alcohol concentration 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 alcohol (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 concentrations of alarm points;
-
Can be used alone alarm buzzer
-
