Reliable for long-term logging
I have been running this sensor for three weeks straight without any issues. The power consumption is low, which is great for battery-operated projects.

Great sensor, tricky initial setup
The sensor itself is very accurate once calibrated. I had a little trouble getting the I2C address right initially, but the documentation helped sort it out quickly.

Easy to integrate
As a beginner, I was worried about wiring this up, but the pinout is clearly labeled. It connected easily to my Arduino Uno and started reading data immediately.

Excellent value for money
Compared to other environmental sensors, this offers the best bang for your buck. The gas detection feature is a nice bonus for indoor air quality monitoring.

High precision readings
The altitude calculation based on pressure is surprisingly accurate. I tested it against a professional barometer and the results were within acceptable margins.
Q: Is the casing waterproof?
A: No, the CJMCU-680 board is not waterproof. It should be used in dry environments or housed in a protective enclosure with breathable membrane for pressure sensing.
Q: Does this board come with headers soldered?
A: No, the board is shipped without headers to allow for flexible mounting options. You will need to solder your own pin headers.
Q: Can this operate at 5V logic levels?
A: The sensor chip operates at 3.3V. While the board has a voltage regulator, the logic lines are not 5V tolerant. Please use a level shifter if connecting to a 5V microcontroller.
Q: What is the accuracy of the temperature reading?
A: The typical temperature accuracy is ±1.0°C within the range of 0°C to 65°C.
Q: Is there a specific library required for the gas sensor function?
A: Yes, we recommend using the Adafruit BME680 library or the Bosch BSEC software library for advanced gas resistance analysis.
