Helps improve office ventilation
We built a simple display using this sensor to show real-time air quality in our meeting room. It has helped us reduce headaches by reminding staff to open windows when CO2 gets high.

Solid performance, small footprint
The module is compact and fits perfectly in my custom enclosure. Readings are consistent. I deducted one star because the pin headers were slightly loose on arrival, but easy to solder.

Excellent precision for home automation
Integrated this into my smart home system easily. The I2C communication is stable, and the CO2 readings match my reference meter very closely. Great value for the price.

Reliable for long-term logging
Been running this 24/7 for two weeks now. No drift observed in the baseline. The UART output is also a nice backup option if I2C bus gets crowded. Very satisfied.

Good for monitoring plant environments
Works well for tracking air quality in my indoor garden. The TVOC data helps me know when to increase ventilation. Only downside is the initial warm-up time takes a few minutes.

Easy to integrate with ESP32
Documentation is clear, and the library support for Arduino and ESP32 is robust. Reading eCO2 and TVOC values simultaneously without issues. Highly recommended for prototyping.
Q: How often does the sensor update its readings?
A: The standard update rate is approximately every 2 seconds, but this can be configured via register settings depending on your specific power consumption and responsiveness requirements.
Q: Is there a Python library available for Raspberry Pi?
A: Yes, several community-driven Python libraries are available on GitHub that support the ENS160 via the smbus2 package for I2C communication on Raspberry Pi.
Q: Does this sensor require calibration before first use?
A: The ENS160 comes pre-calibrated from the factory. It performs an automatic baseline correction during the initial warm-up period, so no manual calibration is typically needed for general use.
Q: What is the difference between CO2 and eCO2 readings?
A: CO2 is the direct measurement of carbon dioxide concentration. eCO2 (equivalent CO2) is an estimated value derived from TVOC and other environmental parameters when direct CO2 sensing is not the primary mode or for cross-verification.
Q: Can this module operate at 5V logic levels?
A: No, the sensor operates at 3.3V. If your microcontroller uses 5V logic, you must use a level shifter for the SDA, SCL, TX, and RX lines to prevent damage to the module.
