Good sensitivity

Detects gas leaks quickly. The potentiometer for sensitivity adjustment is very useful for tuning.

Good value

For the price, you can't beat it. Just remember it needs a long preheat time for stable readings.

Great for home automation

Works perfectly with my ESP32 project. Calibration took some time but detection is accurate for monitoring purposes.

Solid build quality

PCB looks clean. Soldering points are clear. Been running for a week without issues in my workshop.

Easy to integrate

Plug and play with Arduino. Documentation could be better but standard MQ library works fine.
