Great for ESP32 projects

Integrated easily with my ESP32 Home Assistant setup. The library examples worked right out of the box. Very happy with the purchase.

Compact and efficient

Small form factor fits perfectly in my custom enclosure. Power consumption is low enough for battery-operated prototypes.

Perfect drop-in replacement

Swapped this out for my old AGS02MA without any code changes. The I2C address matched perfectly and readings seem consistent with my reference meter.

Works but calibration takes time

The sensor works as advertised, but getting accurate baseline readings required leaving it running for 24 hours in fresh air first.

Reliable TVOC monitoring

Using this to monitor air quality in my workshop. It reacts quickly to solvents and paints. Deducted one star because the documentation could be more detailed.

Good sensitivity, needs warm-up

Works well for detecting cooking fumes and cleaning products. Just remember it needs about 2-3 minutes to stabilize after power-on.

5 FAQ

Q: Can I use this outdoors?

A: While it can function outdoors, the sensor is not weatherproof. You must house it in an enclosure that allows airflow but protects against rain and direct dust.

Q: Is this compatible with Arduino Uno?

A: Yes, it is fully compatible. You just need to connect the SDA and SCL pins to the appropriate I2C pins on your Arduino board.

Q: Does this detect Carbon Monoxide?

A: No, this module is specifically designed for Total Volatile Organic Compounds (TVOC). It is not calibrated for Carbon Monoxide detection.

Q: What is the default I2C address?

A: The default I2C address is typically 0x5A, but please refer to the specific datasheet included in the download link for confirmation.

Q: How long is the warranty period?

A: This product comes with a standard 12-month manufacturer warranty covering defects in materials and workmanship.
