The small currents passing in the sensor is being converted to a voltage that can be read by the ADC. The 16-bit ADC value is received via SPI interface of the EVAL-ADICUP3029 board, where the gas concentration is computed. | The [[adi>en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EVAL-CN0357-ARDZ.html|EVAL-CN0357-ARDZ]] shield circuit provides a potentiostatic circuit for biasing the electrochemical sensor and 16-bit Sigma-Delta ADC.
