High precision confirmed
Used this for a university project monitoring greenhouse conditions. The humidity response time is impressively fast compared to cheaper DHT sensors. Highly recommended for serious projects.

No development needed indeed
Plug and play with any microcontroller that has a UART port. Saves hours of coding time. The data output format is clean and easy to parse.

Great sensor, documentation could be better
The hardware is excellent and precise. However, the baud rate wasn't clearly printed on the module, had to test a few common rates to find it. Once connected, it works flawlessly.

Reliable but runs slightly warm
Accuracy is top-notch. I noticed the module gets slightly warm during operation, which is normal for active sensors, but something to keep in mind for enclosed spaces. Overall very satisfied.

Perfect for quick integration
Exactly as described. The TTL interface made it incredibly easy to connect to my ESP32 without writing complex I2C drivers. Readings are stable and match my calibrated reference meter.

Robust industrial performance
We deployed ten of these in a warehouse environment. They have been running 24/7 for three months with zero drift or failures. The build quality feels very solid.
Q: What is the default baud rate for the serial communication?
A: The default baud rate is typically 9600 bps, but some batches may ship with 115200. Please check the included datasheet or test both rates upon receipt.
Q: Does this support I2C protocol or only UART?
A: This specific 'Serial' version is configured for UART/TTL communication only. If you require I2C, please look for our SHT3x I2C breakout board listing.
Q: Can I power this directly from a 5V Arduino pin?
A: Yes, the module supports a wide voltage range of 3.3V to 5.5V, so it can be safely powered directly from the 5V pin of most Arduino boards.
Q: What is the length of the connecting wires if I buy the wired version?
A: Please note this listing is for the module with header pins only; no wires are included. You will need to solder your own headers or wires based on your project requirements.
Q: Is this module waterproof for outdoor use?
A: The sensor chip itself is resistant to condensation, but the PCB module is not fully waterproof. For outdoor use, we recommend placing it inside an IP65-rated enclosure with a breathable membrane.
