SenseAir Miniature (Carbon Dioxide) CO2 Sensor are non-dispersive small package infrared (NDIR) sensor, a new optical design that enable a precise and accurately measures carbon dioxide level up to 5% that runs on 30mA design for long-term battery or solar powered application. In this demonstration we will going to wire these sensor using CC3200 Simple Link / WiFi IOT Solution with Microcontroller from Texas Instruments. The TI CC3200 LaunchPad XL is a WiFi chip on-board that allows you to operate independently. Follow the illustration below to wired-up the CC3200 IOT board. If you want to use other boards like ESP, STM32, SBC kindly refer to this link.
