Good day,
any body can help me with MG811 sensor,
i connect it in reverse on arduino then not it is in reverse direction and i correct it,
and i determine the + side by multimeter with 1M ohm internal resistor,
now what i should do to get it to work or it damaged?
how i confirm it damage if you think that?
when i get the reading from the MG811 Module is 73 mV only
and reading dose not change when i breath on it
only it change when just power on,
the reading decrease from around 100mV
the sensor powered only on 5V
i didnt power it with else
thanks very much,

i just connect the sensor alone to 5V and read the output from it and it give 650mV
that like it work, and the module board have problem,
any easy way to connect the sensor to Arduino safely?
i think the board i have for MG811 damage,
can i connect the MG811 on MQ135 board?
similar to the following?
can i remove the MQ135 and place the MG811?

i note that the output from the sensor which around 400 mA decrease when it connected to the module!
and it change some time it go to 600mA
but the module decrease the output!
any help?
directly or with some component, in simple way,
because am not electronic engineer,
thanks very much for your help,
