Hello
Me and my mates are making a project redgarding smoking and it's effect on health.
We are going to use the MG-7 carbon monoxide sensor (datasheet; https://www.pololu.com/file/download/MQ7.pdf?file_id=0J313).
We are wondering if this sensor will be able to detect cigarett smoke at for example a restaurant etc.
We are also having trouble finding out how we should build up the circuit around this sensor.
Where does it attach to the arrduino?
