How to: MQ 6 LPG sensor to MSP430G2553


Recommended Posts

Hi All,

 

I am trying to connect MQ-6 LPG Gas sensor to MSP430G2553 launchpad. I am having trouble to interface the sensor to launchpad.

 

From the inernet forums i understood that we can use launchpad TP1/TP3 pins for 5v supply but i am still not clear about the other pins.

 

Can someone help me on the connections and wiring?

Thanks in advance.

It's a 5v sensor, so you're going to have to do something about the 5v output.  A voltage divide might work.  It looks like you're going to need a resistor.  There is some good information at Sparkfun:
