Perfect for my weather station project

These sensors are incredibly accurate and easy to interface with an ESP32. The I2C communication is stable, and the readings match my calibrated reference meter almost perfectly. Highly recommended for DIY enthusiasts.

Industrial grade quality at hobbyist price

We use these in our prototype environmental logging devices. The SHT35 variant offers impressive precision. The digital output eliminates noise issues we had with analog sensors previously. Will definitely reorder.

Easy to use for beginners

As a student new to embedded systems, I found this module very forgiving. There are plenty of libraries available for Arduino that make reading the temperature and humidity trivial. Great learning tool.

Great sensor, minor pin labeling issue

The sensor performance is excellent, providing fast and precise data. The only reason for 4 stars is that the silk screen on the PCB was slightly faint, making it hard to read the pinout initially. Once connected, it works flawlessly.

Reliable humidity monitoring

I bought five of these for my automated greenhouse system. They have been running continuously for three months without any drift or failure. The wide voltage range makes them very flexible for different power setups.

Solid performance

Works exactly as described. Integration with Home Assistant was straightforward using a simple microcontroller. The response time is quick enough for real-time monitoring applications.

5 FAQ

Q: What is the difference between the SHT30 and SHT35 versions listed?

A: The primary difference is accuracy. The SHT35 offers higher precision (±1.5% RH and ±0.1°C) compared to the SHT30 (±2% RH and ±0.3°C). Both share the same form factor and interface.

Q: How do I change the I2C address if I need to connect multiple sensors?

A: This specific module has a fixed I2C address (usually 0x44 or 0x45 depending on the batch). To connect multiple sensors, you would need to use an I2C multiplexer like the TCA9548A, as the address cannot be changed via software or hardware jumpers on this board.

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

A: Yes, the module includes onboard 4.7kΩ pull-up resistors for both SDA and SCL lines, so you can connect it directly to your microcontroller without external components.

Q: Is there a library available for Python on Raspberry Pi?

A: Absolutely. You can use popular libraries like 'sht31' or generic I2C libraries such as 'smbus2' to interact with the sensor. Detailed examples are available in our documentation wiki.

Q: Can I use this sensor in a high-temperature environment like an oven?

A: While the sensor can measure up to 125°C, it is designed for ambient air measurement. Prolonged exposure to extreme heat or direct contact with heating elements may reduce its lifespan. It is best suited for environmental monitoring rather than inside cooking chambers.
