Multi-pixel gas sensor for indoor air quality applications.<br> I 2 C interface with TVOC and CO 2 eq output signals.<br> The SGP40 is a digital multi-pixel gas sensor designed for easy integration into air purifier, demand-controlled ventilation, and IoT applications. CMOSens technology offers a complete sensor system on a single chip featuring a digital I 2 C interface, a temperature controlled micro-type hotplate, and two preprocessed indoor air quality signals. As the first metal-oxide gas sensor featuring multiple sensing elements on one chip, the SGP40 provides more detailed information about the air quality.<br> The sensing elements features an unmatched robustness against contaminating gases present in real-world applications enabling a long-term stability and low drift.<br> Please note:the physical Some color difference or difference, does not affect the use, please do not mind, thank you!<br> Colour:Blue<br> Material:Plastic<br> Package Contents:<br> 2 * Carbon Dioxide Sensor<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
