We recommend that you run this sensor for 48 hours when you first receive it to \"burn it in\", and then 30 minutes in the desired mode every time the sensor is in use. This is because the sensitivity levels of the sensor will change during early use, and the resistance will slowly rise over time as the MOX warms up to its baseline reading.\u003c\/p\u003e\n\u003cp\u003eFor your convenience, we've pick-and-placed the sensor on a PCB with a 3.3V regulator and some level shifting, so it can be easily used with your favorite 3.3V or 5V microcontroller. All of the pins of the BME680 are available on standard 0.100”\/ 2.54mm pitch headers for use with a breadboard.
