Solid Module
Packaging was secure. One pin was slightly bent but easy to fix. Sensor works as advertised.

Good accuracy, slow warmup
Works well but takes a few minutes to stabilize. Good value for the price.

Great for Home Automation
Integrated easily with my ESP32 project. Readings seem consistent compared to my standalone meter.
