Compact and responsive
Small footprint makes it easy to hide inside enclosures. The response time is quick enough for real-time dashboard updates. Highly recommend for DIY smart home setups.

Good accuracy, easy to wire
I bought three of these for my indoor garden monitoring system. They were easy to set up using standard libraries. One unit seemed slightly off on humidity but recalibrated fine.

Perfect for my weather station project
The I2C communication worked flawlessly with my ESP32. The readings are stable and match my reference thermometer very closely. Shipping was indeed fast as advertised.

Solid sensor, clear documentation
The module came well-packaged. Documentation linked in the description helped me get it running in minutes. Only wish the pins were pre-soldered, but that's a minor issue.

Great value for students
Affordable and reliable. Used this for my final year thesis on environmental monitoring. The extended version provides consistent data logs over weeks of testing.

Reliable for long-term logging
Been running this sensor continuously for a month now. No drift in values and no connection drops. The build quality feels robust for the price point.
Q: How often does the sensor need calibration?
A: The sensor comes factory-calibrated. Under normal operating conditions, it maintains accuracy for years. Recalibration is only necessary if exposed to extreme contaminants or physical damage.
Q: Is this compatible with 5V Arduino Uno boards?
A: Yes, the module supports an operating voltage range of 3.3V to 5V, making it fully compatible with the Arduino Uno without needing a level shifter.
Q: Can this sensor be used outdoors directly?
A: The sensor module itself is not waterproof. For outdoor use, you must house it in a breathable, weather-proof enclosure to protect the electronics while allowing air flow for accurate readings.
Q: Does this come with example code for Raspberry Pi?
A: While the physical package includes a quick start guide, you can find comprehensive Python example scripts for Raspberry Pi in the GitHub repository linked in our product description.
Q: What is the maximum cable length for the I2C connection?
A: For reliable I2C communication, we recommend keeping cable lengths under 30cm. For longer distances, please use shielded cables or an I2C extender module.
