Hi friends am doing my mini project in my college in the topic LPG gas sensor as much i have collected all details and materials for it,, the thing i want to know is the sensor is 6 pin'ed but its module is in four pin,, since i have the model of the same project but for co gas, (MQ-7), my question is if i replace the (MQ-6)sensor with that of MQ-7 will work or not?
