Good Value, Needs Calibration

Works well for the price. Just remember to account for the warm-up time in your code logic. Accuracy improves after stabilization.

5 FAQ

Q: How often does the sensor require calibration?

A: We recommend calibration once every 12 months for optimal accuracy under standard operating conditions.

Q: What is the voltage tolerance for this module?

A: The module operates at 5.0 V DC with a tolerance of ± 0.2 V. Please ensure a stable power supply.

Q: Is there cross-sensitivity to other VOCs?

A: There may be some cross-sensitivity to volatile organic compounds. It is best used in environments targeted for formaldehyde detection.

Q: What is the required warm-up time?

A: Typically 3 minutes after power-on is required for the sensor to stabilize and provide accurate readings.

Q: Does this support I2C communication?

A: No, this specific model uses a UART interface only. Please check our product line for I2C compatible options.
