Need co2 levels displayed on lcd in real time in percent. For example 40,000 ppm will be displayed as 4.00%. 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.

Hi, I am new in freelancer but I am an experienced programmer. I had done several programs on micro-controller and know most of its features like USART, ADC, Timer, Interrupt, I2C, SPI etc. and can display the outputs of these features in LCD. As per your description, it seems a good and creative project. I observe that you are using a sensor that gives the level of co2. Now controller compare the sensor output with threshold define and respond according to comparator output i.e. if Sensor>threshold then closed the switch otherwise keep it open. Please tell am I right or wrong? Also I will like to know which type of sensor are you using for checking the level of co2 and what type of output (analog or digital) by the sensor and specify the family of Arduino you are using. Finally I would like to assure you that I can handle this project within specified period of time and give my best to satisfy you. If you are interested to see my work I can send you pictures of simulation related to the features of controller Thanks for your time and consideration.

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.

I have lots of MCU experience (8+ years) and am well-versed in Arduino projects. I have plenty of experience interfacing analog signals to digital MCUs and then formatting the results (as it sounds like you need). I imagine this can be done in a week. I bid for 5 hours a week, but I can work more if it's required. Best regards, -- Chris Bethea
