Customer Reviews (4.6 / 5 · 5 reviews)

Aurora ★★★★★

It took me maybe ten minutes to dial in the potentiometer sensitivity, and now it picks up even a tiny whiff of alcohol vapour during my test runs.

Grace ★★★★★

First time using an MQ3 and I was surprised how quickly it picked up even tiny traces of alcohol vapour. The onboard potentiometer let me tune the sensitivity to my needs in seconds, and the analogue output is clean and easy to read.

Adam D. ★★★★★

The potentiometer makes it easy to dial in the exact sensitivity I need for detecting alcohol fumes. It's been super reliable for my Arduino projects so far.
