Good for esp32 and home assistant
Great sensor, I used it in pair with an esp32 C3 and home assistant with Esphome. Only caveat is that it will show very high peaks due to humidity, so after a hot shower for instance

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.

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

Not functional
Could connect over I2C, but device only ever returned all zeroes.
