| - | The EVAL-CN0357-ARDZ shield circuit provides a potentiostatic circuit for biasing the electrochemical sensor, along with a programmable TIA and 16-bit Sigma-Delta ADC. The TIA converts the small currents passing in the sensor to a voltage that can be read by the ADC. The 16-bit ADC value is received via SPI interface of the EVAL-ADICUP360 board, where the gas concentration is computed. | + | The EVAL-CN0357-ARDZ shield circuit provides a potentiostatic circuit for biasing the electrochemical sensor, along with a programmable TIA and 16-bit Sigma-Delta ADC. The TIA converts the small currents passing in the sensor to a voltage that can be read by the ADC. The 16-bit ADC value is received via SPI interface of the EVAL-ADICUP360 board, where the gas concentration is computed. The ADuCM360_ISM43340_CN0357 application configures the necessary components, processes ADC output value and make all necessary conversions in order to provide the gas concentration in Parts Per Million (PPM). |

| - | At the start of the project, the software computes the necessary parameters and configure the digital rheostat(AD5270) of the TIA. The required parameters are the sensor sensitivity and sensor range. These can be modified by changing the values of the constants SENSOR_SENSITIVITY and SENSOR_RANGE found in the CN0357.h header file of the project. See the “Project Structure” section for more details. | + | For configuring the ISMART Wi-Fi shield, user must enter local Wi-Fi network information such as SSID, password and network security type in the User_Settings.h header file of the project. User is also expected to enter Cloud Instance information such as instance URL, application key and Thing Name in the User_Settings.h file, so data from the sensor can be sent to cloud. See the “Project Structure” section for more details. |
