Arduino and MQ-2 (gas & smoke) sensor - Fritzing

Hooking up an MQ-2 (gas & smoke) sensor to an Arduino Uno via a breadboard. The wiring connection is important: Both A pins and the left H pin need to be connected to 5V. Both B pins need to be connected to the analog input (A0). The right H pin needs to be connected to the ground (GND). A load resistor from 2kOhm to 47kOhm needs to be ...

Gas Sensor using Photon - Fritzing

When using the MQ-2 without a brick or breakout board, you must solder wires to each pin - the two middle pins are the heater coil pins, and must go to a positive rail and negative rail, respectively. The two pins by the side of either middle pins are "A" pins and the other two are "B" pins. A pins must be connected togheter as well as B, but you must choose which one will be the load resistance (the one …
