AJMRTC MQ3 ethanol detection alarm kit is a practical DIY welding assembly kit centered on MQ3 alcohol gas sensor. The sensor features high sensitivity to ethanol vapor and low sensitivity to other interfering gases, which can realize realtime alcohol gas concentration detection and simulate drunk driving alarm scenarios. This kit requires manual soldering assembly, suitable for electronic teaching experiments, student handon practice and hobbyist DIY projects. Users can adjust trigger threshold according to actual demands. When the detected alcohol concentration reaches the set value, alarm signal will be output. It can work well with singlechip microcontrollers for further secondary development. Perfect for electronic welding training, alcohol gas testing prototype making, science experiment projects and related teaching demonstration.
