Frequently Asked Questions

What is the operating voltage range for this sensor?

The sensor requires a stable 5V DC power supply. Operating outside this specified voltage may damage the sensing element or produce inaccurate readings. Ensure your microcontroller or power source can provide a clean 5V rail.

How do I communicate with the sensor and what is the default protocol?

Communication is via a UART (serial) interface. The default baud rate is 115200 bps, but it is often configurable by sending specific command frames. Connect the module's TX and RX pins to your microcontroller's corresponding UART pins, ensuring logic level compatibility (5V).

What gases does this sensor detect and what is its measurement range?

This module detects Total Volatile Organic Compounds (TVOC), Carbon Dioxide (COâ‚‚), and Formaldehyde (CHâ‚‚O). The effective detection range for these gases is from 0.1 parts per million (ppm) up to 100 ppm, making it suitable for indoor air quality assessment.

Is this sensor suitable for outdoor or industrial environments?

Its operating temperature range of -20°C to 50°C allows for use in many controlled outdoor and indoor settings. However, for harsh industrial environments with extreme temperatures, high humidity, or corrosive gases, a sensor with a corresponding IP rating and more robust housing would be recommended.
