Reliable for long-term logging
Been running these sensors for three months straight without any failures. The data consistency is impressive. Highly recommend for anyone building environmental loggers.

Solid performance
Works exactly as described. I integrated four of these into a multi-room monitoring system. Communication is stable over long wires. Just ensure you have the correct pull-up resistor.

Good value, reliable readings
Using these to monitor humidity in my greenhouse. They seem consistent and hold up well against moisture. One star off because the header pins were slightly bent upon arrival, but easy to fix.

Great for beginners
As someone new to electronics, this module was very easy to integrate. Plenty of tutorials online for the DHT22 variant. Reads temperature and humidity instantly on my LCD screen.

SHT30 is worth the extra cost
Don't hesitate to get the SHT30 model if you need precision. The response time is fast, and it doesn't drift like cheaper sensors. Excellent build quality on the PCB.

Perfect for my weather station
I bought the SHT30 version for a home weather station project. The accuracy is noticeably better than the older DHT11 modules I used previously. Setup with my ESP32 was straightforward using standard libraries.
Q: Do I need to buy a separate resistor for this to work?
A: Most of our modules come with a built-in pull-up resistor on the PCB. However, if you are building a custom circuit from scratch, a 10k ohm resistor is recommended.
Q: Can these sensors be used outdoors in the rain?
A: The sensor module itself is not waterproof. For outdoor use, you must house it in a breathable, weather-proof enclosure to protect the electronics while allowing air flow.
Q: Which library should I use for the SHT30 model?
A: For the SHT30, we recommend using the 'Adafruit SHT31' library or the generic 'SparkFun SHT31' library, as they support the I2C communication protocol used by this specific sensor.
Q: What is the difference between the DHT11 and DHT22 versions listed?
A: The DHT22 offers higher accuracy and a wider temperature/humidity range compared to the DHT11. The DHT22 is generally preferred for precise applications.
Q: Is this module compatible with 5V Arduino Uno boards?
A: Yes, this module operates within the 3.3V to 5.5V range, making it fully compatible with the 5V logic of the Arduino Uno.
