NO2 click

MIKROE-3098 LMP9100SD

NO2 click is a very accurate nitrogen-dioxide gas sensor Click board™, equipped with the SPEC amperometric gas sensor which electrochemically reacts with the nitrogen-dioxide (NO2). It is supported by the LMP91000, a high-precision integrated analog front-end IC (AFE), perfectly suited for use in electrochemical sensing applications. The Click board™ also 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.
