We provide a library for the Alcohol3 Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
The library initializes and defines the I2C bus driver and drivers that offer a choice for reads adc data from I2C. The library includes function for reads CO data in the AIR (in ppm and mg/L), function for reads Ethanol data in ppm and reads the percentage of alcohol in the blood (BAC).
Key functions :
float alcohol3_getPercentageBAC()
- Function for read percentage of alcohol in the blood (BAC)uint16_t alcohol3_ethanolInPPM()
- Function for read Ethanol (C2H5OH) data in ppmuint16_t alcohol3_getCOinPPM()
- Function for read CO (Carbon monoxide) data in ppm
Examples Description
The application is composed of three sections :
- System Initialization - Initializes I2C module
- Application Initialization - Initialization driver init
- Application Task - (code snippet) - Reads percentage of alcohol in the blood (BAC) and this data logs to USBUART every 1 sec.
void applicationTask()
{
uint16_t CO_ppm;
uint16_t pBAC;
char demoText[ 50 ];
mikrobus_logWrite(" --- Alcohol diagnostics ----", _LOG_LINE);
CO_ppm = alcohol3_getCOinPPM();
WordToStr(CO_ppm, demoText);
mikrobus_logWrite(" CO in ppm | ", _LOG_TEXT);
mikrobus_logWrite(demoText, _LOG_LINE);
pBAC = alcohol3_getPercentageBAC() * 1000;
WordToStr(pBAC, demoText);
if( 10 > pBAC && pBAC < 100 )
{
mikrobus_logWrite(" BAC | 0.00", _LOG_TEXT);
LTrim(demoText);
mikrobus_logWrite(demoText, _LOG_LINE);
}
else if(100 <= pBAC && 1000 > pBAC)
{
mikrobus_logWrite(" BAC | 0.0", _LOG_TEXT);
LTrim(demoText);
mikrobus_logWrite(demoText, _LOG_LINE);
}
else if ( pBAC >= 1000)
{
mikrobus_logWrite(" BAC | 0.", _LOG_TEXT);
LTrim(demoText);
mikrobus_logWrite(demoText, _LOG_LINE);
}
else
{
mikrobus_logWrite(" BAC | 0.0000", _LOG_LINE);
}
mikrobus_logWrite(" ----------------------------", _LOG_LINE);
mikrobus_logWrite( " " , _LOG_LINE);
Delay_ms( 1000 );
}
The full application code, and ready to use projects can be found on our LibStock page.

- UART
Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
