Pololu MQ Gas Sensor Carrier board for MQ3, MQ2, MQ4 + many other gas sensors

$1.95

Our line of MQ and other similar Gas and Fume sensors have proven to be an invaluable addition to our wide array of available sensors, and this board makes using them even easier by creating the needed circuit for most of the MQ boards and simultaneously making it possible to connect your sensors directly to a solderless breadboard, or easily integrate it into your project of choice.

The board even has a place where you can solder your own load resistor in to help fine tune the output of your sensor (refer to your MQ sensors datasheet for more details on load resistance calibration).

If you are interested in using gas and fume sensors in your project you should definitely pick up several of these boards.
