Ozone 3 Click is a compact add-on board suitable for ozone concentration detection and monitoring. This board features the 110-407, a high-performance ultra-thin electrochemical gas sensor from SPEC Sensors supported by the LMP91000, a high-precision integrated analog front-end IC (AFE) ideal for this sensing application. It 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. This Click board™ represents an ideal choice for health, environmental, industrial, and residential monitoring.

Click library

  • Author : Nenad Filipovic
  • Date : Apr 2021.
  • Type : I2C type

Software Support

We provide a library for the Ozone3 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on mikroE github account.

Library Description

This library contains API for Ozone3 Click driver.

Standard key functions :

  • ozone3_cfg_setup Config Object Initialization function.

    void ozone3_cfg_setup ( ozone3_cfg_t *cfg );
  • ozone3_init Initialization function.

    OZONE3_RETVAL ozone3_init ( ozone3_t *ctx, ozone3_cfg_t *cfg );
  • ozone3_default_cfg Click Default Configuration function.

    void ozone3_default_cfg ( ozone3_t *ctx );

Example key functions :

  • ozone3_read_adc Ozone 3 read ADC function.

    uint16_t ozone3_read_adc ( ozone3_t *ctx );
  • ozone3_get_o3_ppm Ozone 3 get O3 ppm function.

    float ozone3_get_o3_ppm ( ozone3_t *ctx );

Example Description

This library contains API for the Ozone 3 Click driver. This demo application shows an example of the O3 ppm data measurement.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART. After driver initialization the app set default settings.


void application_init ( void ) {
    log_cfg_t log_cfg;        /**< Logger config object. */
    ozone3_cfg_t ozone3_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.

    ozone3_cfg_setup( &ozone3_cfg );
    OZONE3_MAP_MIKROBUS( ozone3_cfg, MIKROBUS_1 );
    err_t init_flag = ozone3_init( &ozone3, &ozone3_cfg );
    if ( init_flag == I2C_MASTER_ERROR ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    ozone3_default_cfg ( &ozone3 );
    log_info( &logger, " Application Task " );
    Delay_ms ( 300 );
}

Application Task

This is an example that shows the use of a Ozone 3 Click board™. Get and logs O3 ( Trioxygen ) data as ppm value. Results are being sent to the Usart Terminal where you can track their changes.


void application_task ( void ) {
    float o3_ppm = ozone3_get_o3_ppm( &ozone3 );
    log_printf( &logger, "\tOzone : %.2f ppm \r\n", o3_ppm );
    Delay_ms ( 500 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on mikroE github account.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Ozone3

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. UART terminal is available in all Mikroelektronika compilers.

RMS to DC 2 Click

0

RMS to DC 2 Click is a compact add-on board that converts the RMS of the input signal into a DC voltage. This board features the AD8436, a low-cost, low-power, true RMS-to-DC converter from Analog Devices. The AD8436 is a translinear precision, low-power, true RMS-to-DC converter that delivers true RMS or average rectified value of AC waveform. It features high accuracy, a wide dynamic input range (100μV rms to 3V rms), a wide bandwidth of up to 1MHz, and more. This Click board™ makes the perfect solution for the development of various true RMS digital multimeter applications, panel meters and gauges, AC + DC measurement applications, a true RMS measurement of an audio signal, and other similar applications that require accurate RMS value readings.
