I want to detect a certain range of CO and LP gas but it is in ppm. But the problem i do not know what is the equivalent value since sensor detects in voltage (0-5 V). i need some conversion for it. for example i need 35ppm of CO, how do i know what is the voltage that is equivalent (between 0-5 V) that is equivalent to 35ppm

Hi there, I'm an electronic engineer,I can design this circuit perfectly. I'm an expert in Eagle CAD,EasyEDA and Altium Designer. Can you please send me a message,So we can discuss more about the project? I can come up with an equation to convert the voltage to PPM Value,So you can measure the gas. Design is a huge part of my life and I work hard to produce the highest quality, effective, innovative, timeless, designs that my clients will love and I would love to work with you!! :) Thank you Achini

At the end, You will get a source code containing the code that converts the ppm to the voltage. I also keep the price low so that You wont be bothered with the price Relevant Skills and Experience I am an experienced robotics researcher. I am currently a member of two research labs located in the capital city of Turkey.

Connect the MQ-6 and MQ-7 to an Analog to Digital Converter (ADC) and with the conversion formula on the datasheet you will get the ppm value. Cheers

Currently i am also working with CO2 values for my plants optimum CO2 lvl calculation. , I can help you to the some extends.(Around 5mV) but you need more precisement such as nV level. You should multiple your budget with 10 or 100.

Dear Sir, I have read the project description very carefully. You wanted to detect and measure gases in ppm( parts per million) unit. May be I can help you. I am studying Electronics Engineering. It is an easy task. It can be done by Arduino. Not needed much time. But I need to know more information,,,, * do you need the code only? * do you have any other demand? I would like to talk with you about it. Best regards, Md. Mubin
