Good value, clear documentation
The sensor works well out of the box. The breakout board makes it easy to prototype without needing a microscope for soldering. Deducted one star only because the pin headers were not included, but that is a minor issue.

Perfect for plant monitoring
Stable readings over long periods. I have three of these running in my automated greenhouse system, and they haven't drifted at all in two months. The humidity response is surprisingly fast.

Excellent precision for hobby projects
I used this module for a home weather station project. The I2C communication was straightforward with my Arduino, and the readings matched my calibrated reference meter almost perfectly. Highly recommended for DIY enthusiasts.

Solid industrial grade performance
Using this in a small enclosure to monitor server room conditions. It handles the temperature fluctuations well. Just ensure you pull up the SDA and SCL lines correctly, as the module does not have onboard pull-ups.

Easy library integration
Worked immediately with standard SHT3x libraries on ESP32. No calibration needed for my use case. The data consistency is impressive compared to cheaper DHT sensors I used previously.

Best sensor in this price range
Compact, accurate, and reliable. I've tested it against a professional hygrometer and the deviation is negligible. Great addition to any IoT toolkit.
Q: Can this sensor operate at 3.3V logic levels?
A: Yes, the GT-HT30 module supports an operating voltage range of 2.4V to 5.5V, making it fully compatible with both 3.3V and 5V microcontroller systems.
Q: How often should I recalibrate this sensor?
A: The SHT30 is factory calibrated and generally maintains accuracy over its lifetime under normal operating conditions. Recalibration is typically only necessary if the sensor is exposed to extreme chemicals or physical damage.
Q: What is the default I2C address for this sensor?
A: The default I2C address is usually 0x44. Some versions allow changing the address to 0x45 by bridging a specific pad on the PCB, please refer to the schematic in the datasheet.
Q: Does this module come with pre-soldered header pins?
A: No, the module typically ships without header pins to allow for flexible mounting options. You will need to solder your own headers or wires depending on your setup.
Q: Is there a protective coating on the sensor element?
A: The SHT30 sensing element has a standard polymer protection filter which guards against dust and most contaminants, but it is not waterproof for submersion.
