Hi All,
I am designing a circuit that detects the CO in the air.
I bought the carbon monoxyde sensor called (MQ 307 hanwei manufacturer) but unfortunately i didn't find on the net any docs related to it.
i ve just found the datasheet which didn't help me too much analysing its operation sad.gif
All the docs i found are related to figaro sensor that have 4 pins while mine has 3 pins
Please can anyone help
Thanks in advance
