Reliable SHT30 performance

Using the SHT30 variant for a greenhouse monitor. It handles the high humidity environment well without drifting. The wide voltage range makes it versatile for different microcontrollers.

Solid industrial grade sensor

We deployed ten of these in a server room monitoring setup. They have been running for three months without failure. Response time is quick enough for our logging intervals.

Easy library integration

Worked immediately with the standard Adafruit SHT31 library. No complex calibration needed out of the box. Great value for the price.

Perfect for Arduino Projects

This module works flawlessly with my Arduino Uno. The I2C address was easy to find in the datasheet, and the readings are very stable compared to cheaper analog sensors.

Great first sensor module

As a beginner, I found this very easy to wire up. The labeling on the board is clear (VCC, GND, SDA, SCL). Highly recommend for anyone starting with environmental sensing.

Good accuracy, clear documentation

Bought this for a home weather station. The temperature accuracy is impressive. Only giving 4 stars because the pin headers were slightly loose upon arrival, but a quick solder fixed it.

5 FAQ

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

A: Yes, this breakout module includes built-in 4.7kΩ pull-up resistors on both SDA and SCL lines, so you can connect it directly to your microcontroller.

Q: How do I distinguish between SHT20 and SHT35 models visually?

A: The specific model number is usually printed on the white sensor element mounted on the PCB. Additionally, the product SKU on the packaging will specify exactly which variant (SHT20, SHT30, etc.) you purchased.

Q: Is the sensor waterproof or suitable for outdoor use?

A: The sensor chip itself is robust, but the breakout board is not waterproof. For outdoor use, we recommend placing the module inside a breathable weatherproof enclosure to protect the electronics while allowing air flow.

Q: What is the default I2C address for the SHT30 version?

A: The default unicast I2C address for the SHT30 is typically 0x44. Some modules allow changing this to 0x45 via a hardware strap if available on the specific PCB design.

Q: Can I use this with a 3.3V Raspberry Pi?

A: Absolutely. The module supports a wide voltage range from 3.3V to 5.5V, making it fully compatible with 3.3V logic systems like the Raspberry Pi.
