    Questions and Answers

    I found that the sensor pins are identical from other sensors. Can I replace or remove the sensor from one driver to another driver? Can I buy a CO2 sensor from the 3rd party and wire it on the Grove Gas driver?

    Hey , if the circuit is the same, then it will be possible. We don't know what sensor you will buy and how you use that. The warning is at own risk. But happy hacking :)
