Hi all.
I have this sensor: MQ6 + LM393
I have measured electric continuity between GND pin and Vcc pin with a multimeter. There are electric continuity between those pins (biiiiiiiii).
I want to use Vcc and GND with others sensors on the same line.
Can I do this?... or have I to put more electronic before (like op insulation transistor)?
Cheers!
The resistance between Vcc and GND is 40 ohms (more or less).
What do you think about to use those lines with others sensors?
On the sensor working with Arduino, his input current is 110mA.
Hi!.
Its normal usage. There aren't problems if you try with 2 capacitors 470uf 100nf.
Cheers.
LM393 is a voltage comparator that serves only for the digital output (in connection with the know).
