Good accuracy
The SHT30 is much better than the DHT11. Slightly pricey but worth it for the precision in my greenhouse setup.

Reliable sensors
Bought 10 units, all working. Good for greenhouse monitoring. Stable readings over several weeks of testing.

Easy to use
Needed a pull-up resistor but works great now. Make sure to check the wiring diagram before connecting power.

Great for Arduino projects
Works perfectly with my Uno. Easy to wire up and the library support is excellent. Reading data was straightforward.

Perfect for school project
Arrived quickly. Documentation was helpful for a beginner like me. Got my science fair project working in no time.
Q: Is the sensor waterproof?
A: The module itself is not waterproof. Use a probe version if you need to measure liquids or high moisture environments.
Q: What is the pinout?
A: Typically VCC, DATA, and GND. Please check the diagram in the product description for specific module orientation.
Q: Does this work with 3.3V logic?
A: Yes, most modules support 3.3V to 5V input. Please check the specific model datasheet for voltage tolerances.
Q: How fast can I read data?
A: DHT11 is 1Hz, DHT22 is 0.5Hz. SHT30 is faster and supports higher sampling rates.
Q: Which library should I use?
A: We recommend the Adafruit DHT or SHT libraries available in the Arduino Library Manager.
