Fartosensor (MQ4) – Wackydeveloper

Jan 07, 2017· The MQ4 sensor can get pretty hot, so take care if you’ve kept it running for a while! The sensor must be calibrated for production use, so do not expect an 100% accurate result. Start out by figuring out what components can handle 5V and what components can’t. If you connect a component that cant handle 5V you may destroy the component.
