The CO 2 Click Board™ is a very accurate, carbon-monoxide-gas-sensor Click Board™, equipped with the SPEC amperometric, 3SP CO 1000 gas sensor which electrochemically reacts with the carbon monoxide (CO). It is supported by the LMP91000, a high-precision integrated analogue front-end IC (AFE), perfectly suited for use in electrochemical, sensing applications.
The CO 2 Click Board™ also provides the reference voltage required by the sensor and it offers a choice between the analogue output from the AFE IC buffered with the low noise op-amp, and the digital output from the 12-bit SAR A/D converter.
