How to Use Carbon Dioxide CO2 IR Sensor in Raspberry Pi

This is SenseAir Miniature Air Sensing (Carbon Dioxide) CO2 Sensor
featuring a 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 power application. This device has a full control integration from the host system, a flexible CO2 measurements period to minimize power consumption in the fields of implementation. For one measurement requires only 3.6 mC energy 11.8 mJ at 3.3v on the battery. This device provides a flexible and simple communication protocol which lets you change the measurement period, compensate for barometric pressure, control and calibration in real time. Background ABC and 0 gas calibration method are both implemented in a simple ways. There are two types for model which this device family has, the SenseAir L8 and S8. The S8 has also two version each version has its own sensing percentage of detection base on applications. The 0-1% sensor is design for residential applications, while the 0-5% sensor is designed for commercial device provides simple communication via UART.
