Ozone click carries MiCS-2614, a compact MOS sensor for ozone (O3) detection. Ozone click is designed to run on a 5V power supply. It communicates with the target microcontroller over SPI interface.

MiCS-2614 features

MiCS-2614 is a small (5 x 7 x 1.55mm) MEMS sensor consisting of a micromachined diaphragm with an embedded heating resistor and the sensing layer on top.

Its detection range is from 10-1000ppb.

The sensor outputs an analog voltage, which is converted by the onboard MCP3201 12-bit ADC converter.

Key features

  • MiCS-2614 sensor for ozone
    • Detection range: 10-1000ppb
    • Robust MEMS sensor for harsh environments
  • SPI interface
  • 5V power supply

Features and usage notes

The sensor outputs an analog voltage, which is converted by the onboard MCP3201 12-bit ADC converter. The MCP3201 is typically used as a sensor interface for data acquisition. It’s capable of outputting sample rates of up to 100 ksps at a clock rate of 1.6 MHz.

Note that the sensing layer is sensitive to various external factors. For example, it must not be exposed to high concentrations of organic solvents, silicone vapours or cigarette-smoke. Otherwise it might damage the sensitive layer and diminish the accuracy of the sensor.

Programming

The following code snippet reads off the sensor data every 500 milliseconds.

 1 void main() 
 2 {
 3    system_init();
 4    display_init();
 5    
 6    while( 1 )
 7    {
 8        measurement();
 9        calculation();
10        display_result();
11        delay_ms( 500 );
12    }
13 }

Code examples that demonstrate the usage of Ozone click with MikroElektronika hardware, written for mikroC for ARM, AVR, dsPIC, FT90x, PIC and PIC32 are available on Libstock.
