Does anyone know how to wire a MC105 gas sensor (see http://www.conrad.com/ce/en/product/183305/MC105-Gas-Sensor-x-H-122-mm-x-88-mm).
Thanks!
Did you download and look at the accompanying document?
http://www.produktinfo.conrad.com/datenblaetter/175000-199999/183305-in-01-en-GAS_SENSOR_MC105.pdf
It contains two recommended circuit diagrams.
Thanks for the link!
Still find it hard to see how to wire it to an arduino board...
Any ideas?
Hi, looking at the first circuit, think of the single chip device as the arduino.
You connect the output of the circuit, R11 to an analog input of the arduino.
Program the arduino to read the analog input, then program what you want it to do next.
It looks like the circuit outputs a variable voltage, dependent on gas concentration.
