Ammonia click is an Ammonia detection (NH3) sensor, based on the MQ-137 gas sensor. This gas sensor has a sensitive layer made of SnO2, which changes its resistance when exposed to ammonia. The sensor is able to sense NH3 concentration in the range of 5 ppm to 200 ppm.

Library Description

The library covers all the necessary functions to control Ammonia click board. User can, turn heater on or off and read ADC value.

Key functions:

  • void ammonia_heater ( uint8_t state ); - Function is used to turn the heater on or off.
  • uint32_t ammonia_data_read ( ); - Function is used to read ADC value.
  • uint32_t ammonia_adc_read( ); - Function reads ADC values.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes SPI module, LOG structure, sets CS and PWM pins as output and MISO and AN pins as input.
  • Application Initialization - Initalizes SPI or ADC driver, turns on the heater, and makes an initial log.
  • Application Task - (code snippet) This is an example that shows the capabilities of the ADC 9 click by reading ADC value and displaying it via UART.
void application_task ( )
{
    if ( interface_sel == AMMONIA_INTF_SPI )
    {
        spi_value = ammonia_data_read( );

        LongWordToStr( spi_value, log_txt );
        Ltrim( log_txt );
        mikrobus_logWrite( "ADC value: ", _LOG_TEXT );
        mikrobus_logWrite( log_txt, _LOG_LINE );
    }
    else
    {
        adc_value = ammonia_adc_read( );

        WordToStr( adc_value, log_txt );
        Ltrim( log_txt );
        mikrobus_logWrite( "ADC value: ", _LOG_TEXT );
        mikrobus_logWrite( log_txt, _LOG_LINE );
    }
    mikrobus_logWrite( "--------------------", _LOG_LINE );
    Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

  • I2C
  • ADC
  • UART
  • Conversions

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.
