Student Favorite

We bought a bulk pack for our university lab. Students find it easy to wire up, and the library support for ESP32 and Raspberry Pi is robust. No failures so far after two months of heavy use.

Accurate and Reliable

I am using three of these in my home greenhouse setup. The humidity accuracy is impressive, helping me maintain optimal conditions for my plants. The build quality of the breakout board is also excellent.

Great Sensor, Minor Pin Labeling Issue

The sensor itself is top-notch with fast response times. I deducted one star because the pin labeling on the back was slightly faint, making it hard to read under low light. Otherwise, it performs exactly as specified.

Best in Class for Price

Switched from SHT21 to this SHT30 model and noticed an immediate improvement in stability during rapid temperature changes. It handles condensation well without drifting. Excellent value for money.

Solid Performance

Works great for my outdoor weather station enclosure. Just make sure to conformal coat the board if you are using it in very high humidity environments long-term, though the sensor chip itself is quite robust.

Perfect for Arduino Projects

This SHT30 module works flawlessly with my Arduino Uno. The I2C communication is stable, and the readings are very consistent compared to my old DHT22 sensor. Highly recommended for anyone needing precise environmental data.

5 FAQ

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

A: The default I2C address is 0x44. There is also an alternative address of 0x45 available if you bridge the specific pad on the back of the module.

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

A: The SHT30 comes factory-calibrated and generally does not require user calibration. If readings seem incorrect, please check your wiring, ensure proper power supply, and verify that you are not generating heat near the sensor during measurement.

Q: Does this module come with pull-up resistors for the I2C lines?

A: Yes, the breakout board includes 4.7kΩ pull-up resistors on both SDA and SCL lines, so you can connect it directly to your microcontroller without extra components.

Q: Can this sensor be used with 3.3V logic only?

A: Absolutely. The SHT30 operates within a voltage range of 2.4V to 5.5V, making it fully compatible with both 3.3V and 5V logic systems.

Q: Is there a library available for Python?

A: Yes, there are several open-source Python libraries available for Raspberry Pi and generic Linux systems that support the SHT30 via the smbus2 package.
