High precision as advertised
Tested against a calibrated reference unit in our lab. The deviation was minimal within the expected range. Excellent component for professional prototypes.

Perfect for my air quality monitor project
This module integrated seamlessly with my ESP32 setup. The readings are consistent and match my standalone commercial detector very closely. Great value for the precision offered.

Low power consumption is accurate
I am running this on battery power for a portable device. The low power claim holds true, and the battery life is excellent. The UART output is clean and easy to parse.

Solid performance for the price
Not industrial grade, but perfect for home automation systems. It gives me peace of mind knowing I can track VOC levels continuously. Documentation could be slightly better.

Compact and reliable
The size is incredibly small, fitting easily into my custom enclosure. Response time is fast when exposed to test samples. Highly recommend for hobbyist projects.

Good sensitivity, needs warm-up
Works well after a 2-minute warm-up period as stated in the datasheet. It detected formaldehyde from new furniture quickly. Just make sure your power supply is stable.
Q: Does this module require external calibration before first use?
A: No, the sensor comes factory pre-calibrated. However, we recommend allowing a 2-minute warm-up time upon first power-up for optimal stability.
Q: Is the communication protocol compatible with Arduino Uno?
A: Yes, it supports UART which is fully compatible with Arduino Uno. You can also use the I2C interface if your specific firmware version supports it.
Q: Can this detect other gases like benzene or toluene?
A: This module is specifically tuned for formaldehyde. While electrochemical sensors may have some cross-sensitivity to other VOCs, accurate quantification is only guaranteed for formaldehyde.
Q: What is the expected lifespan of the sensor element?
A: Under normal operating conditions, the sensor element has an expected lifespan of approximately 2 to 3 years before replacement is recommended.
Q: What is the maximum operating humidity for this sensor?
A: The sensor operates best between 15% and 90% Relative Humidity (non-condensing). Performance may degrade in condensing environments.
