Reliable for HVAC monitoring

Installed three of these modules to monitor different zones in my home HVAC system. They communicate reliably over long I2C bus lines when using proper pull-up resistors. Very satisfied with the build quality.

Easy to integrate with Arduino

Connected this to my Arduino Uno using standard libraries. No special drivers needed beyond the usual SHT30 libraries. Data logging has been stable for over a week now without drift.

Perfect drop-in replacement

I needed a sensor compatible with my existing SHT30 codebase, and this CJ-GXHT30 worked flawlessly right out of the box. The I2C address matched perfectly, and the readings are consistent with my calibrated reference meter.

Great accuracy for the price

Using these in a small automated greenhouse project. The humidity response is quick, and the temperature stability is impressive. Only giving 4 stars because the breakout pins were slightly bent upon arrival, but easy to fix.

Good for university projects

Bought this for a final year instrumentation project. It provides precise data for our weather station prototype. The documentation could be slightly more detailed regarding power consumption modes, but overall it works well.

Bulk order success

Purchased ten units for our community maker space. All units tested functional with identical performance characteristics. Great value for educational workshops on environmental sensing.

5 FAQ

Q: How do I calibrate the sensor if readings seem off?

A: The sensor comes factory-calibrated. If readings appear incorrect, ensure there are no heat sources nearby affecting the temperature. Software offset calibration can be applied in your code if comparison with a reference device shows a constant deviation.

Q: Is this module compatible with 3.3V logic levels?

A: Yes, the CJ-GXHT30 operates within a voltage range of 2.4V to 5.5V, making it fully compatible with both 3.3V and 5V microcontroller logic levels.

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 enclosure that protects against rain and direct sunlight while allowing air circulation for accurate humidity reading.

Q: What is the default I2C address for this sensor?

A: The default I2C address is 0x44. Some variants may also respond to 0x45 depending on the ADDR pin configuration, but 0x44 is the standard for direct SHT30 replacement.

Q: Do I need to install specific drivers for Raspberry Pi?

A: No specific drivers are required. You can use standard Python libraries like Adafruit_CircuitPython_SHT31 or similar SHT30-compatible libraries available for Raspberry Pi.
