Excellent value for money
Compared to other sensors in this price range, the SHT30 offers superior stability. It has been running continuously for two weeks without any drift or communication errors.

Compact and precise
Small form factor fits perfectly inside my custom 3D printed enclosure. Temperature and humidity data updates quickly, which is essential for my HVAC control logic.

Great for learning embedded systems
Used this for my university final year project. The library support for ESP32 is excellent. The only minor issue was that the PCB silk screen was slightly faint, but the datasheet helped.

Reliable sensor module
I have tested three of these units, and they all provide identical readings in the same environment. The I2C address is standard, making integration into existing projects seamless.

Perfect for my weather station
This module works flawlessly with my Arduino setup. The readings are consistent and match my calibrated reference meter very closely. Setup was easy using standard libraries.

Good accuracy, clear documentation
Bought this for a greenhouse monitoring project. The humidity response time is quite fast. Only giving 4 stars because the pin headers were not included, but soldering them on was simple.
Q: Which Arduino library do you recommend for this?
A: We recommend using the 'Adafruit SHT31' library or the generic 'SHT3x' libraries available in the Arduino Library Manager, as they support the SHT30 chip seamlessly.
Q: What is the default I2C address for this sensor?
A: The default I2C address for the GY-SHT30-D module is 0x44. Some variations might use 0x45 depending on the ADDR pin configuration.
Q: Is this compatible with 3.3V logic levels?
A: Yes, the module operates within a voltage range of 2.4V to 5.5V, making it fully compatible with both 3.3V and 5V microcontrollers like ESP32 and Arduino.
Q: Does this module come with pre-soldered headers?
A: No, the module typically comes without headers to allow for flexible mounting options. You will need to solder your own pin headers or wires.
Q: Can I use this outdoors in the rain?
A: The sensor chip itself is robust, but the PCB is not waterproof. For outdoor use, you must house the module in a waterproof enclosure with a breathable membrane for humidity sensing.
