Reliable in high humidity
Using this in my greenhouse monitoring setup. It handles the high humidity environment very well without drifting. The build quality of the breakout board is solid.

Good accuracy, easy integration
Integrated this into my home automation system. The data is reliable and the response time is quick. Only giving 4 stars because the pin headers were not included, but soldering them was easy.

Solid performance
Works as expected. The voltage range is flexible enough for both 3.3V and 5V logic systems. Delivery was fast and packaging protected the sensitive components well.

Perfect for Arduino projects
This sensor module works flawlessly with my Arduino Uno. The I2C communication is stable, and the readings are consistent with my calibrated reference meter. Highly recommended for hobbyists.

Best value SHT31 module
Compared to other vendors, this offers the best price-to-performance ratio. The sensor wakes up quickly from sleep mode, which is great for battery-powered applications.
Q: Is there a library available for ESP32?
A: Yes, this sensor is compatible with the standard Adafruit SHT31 library and the Sensirion official libraries, both of which support ESP32.
Q: What is the default I2C address?
A: The default I2C address for the GY-SHT31-D is typically 0x44. Some variations might use 0x45 depending on the ADDR pin configuration.
Q: Does it support high repetition mode for faster reading?
A: Yes, the SHT31-D supports both high and low repetition modes. You can configure this via the command register to balance between speed and power consumption.
Q: Can this be used outdoors directly?
A: While the sensor chip itself is robust, the breakout board is not waterproof. For outdoor use, please house it in a weatherproof enclosure with proper ventilation.
Q: Does this module come with pin headers pre-soldered?
A: No, the module is shipped without pin headers to allow for flexible mounting options. You will need to solder them yourself if required.
