Alcohol 2 Click Board
Alcohol 2 Click Board
The Alcohol 2 Click Board™ is a very accurate ethanol gas (alcohol) sensor Click Board™, equipped with the SPEC amperometric gas sensor which electrochemically reacts with the ethanol. It is supported by the LMP91000, a high-precision integrated analog front-end IC (AFE), perfectly suited for use in electrochemical sensing applications. The Click Board™ also provides the reference voltage required by the sensor and offers a choice between the analog output from the AFE IC buffered with the low noise op-amp, and digital output from the 12-bit SAR A/D converter.
Software Support
We provide a demo application for the Alcohol 2 Click Board™ 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 writing data in a register. The library includes the function for reading the Alcohol data.
Key functions :
uint16_t alcohol2_readAlcohol()
- Function for reading the Alcohol data
void alcohol2_writeByte( uint8_t reg, uint8_t _data )
- The function writes one byte to the register.
Example Description
The application is composed of three sections:
- System Initialization - Initializes I2C bus and set AN pin as INPUT and RST pin as OUTPUT.
- Application Initialization - Initializes I2C driver and device configuration.
- Application Task - (code snippet) - Gets Alcohol (C2H5OH) data and logs data to USBUART every 500ms.
void applicationTask() { Alcohol_Value = alcohol2_readAlcohol(); FloatToStr( Alcohol_Value, demoText ); mikrobus_logWrite( "Alcohol value : ", _LOG_TEXT ); mikrobus_logWrite( demoText, _LOG_LINE ); Delay_ms( 500 ); }
The full application code and ready to use projects can be found on our LibStock page.
mikroE Libraries used in the example:
- I2C
- Conversions
Additional Notes and Information
Depending on the development board you are using, you may need a 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.
MIKROSDK
The Alcohol 2 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant click board demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
