DIY Breath Analyzer With The MQ3
I always wanted to build some project with a MQ Sensor. The MQ3 alcohol gas concentration sensor is perfect for this case! I designed a pcb with a small size and battery powered operation. And with that my DIY Breath Analyzer was born! You can check out my instructable to read more about the process and build yourself one too!:
