Simple, Reliable, and ESP32-Friendly
This gas sensor works exactly as intended. It’s a great size—compact enough to fit into small projects—and was super easy to work with. I had it connected to an ESP32 with no issues at all, and it started delivering reliable readings right away.If you’re looking for a no-fuss gas sensor that just works, this is a solid choice. Highly recommended for maker projects.

Works great
The review thing asked for motion detection, I rate that 1 star as this is not a motion detector. As a gas detector it works great!!! 5 stars all the way.
8**5
Not functional
Could connect over I2C, but device only ever returned all zeroes.

We need to check
One of the two sensors turned out to be inoperative.
