Arduino LCD Shield Keypad for Sensor

Need co2 levels displayed on lcd in real time in percent. For example 40,000 ppm will be displayed as [url removed, login to view]%. It will also show the valve status (open or closed) Buttons on LCD will control the co2 threshold. Once the co2 reaches the threshold the valve goes off. Below the threshold the valve is open. Threshold is set in percent as well. So if set at 4% the valve will stay open until it reaches 4% and then close.

Let me know if you have further clarifications.

Skills: Arduino, Electrical Engineering, Electronics, Microcontroller

Made a similar project using ADC on PIC 16 doing it on arduino would not be much of a deal given the adequate sensors are available.
