Perfect for greenhouse
Monitoring my plants with these sensors. I bought a mix of DHT20 and SHT30. They handle the humidity well. No condensation issues so far.

Great for beginners
Used the DHT11 for my school project. It was easy to wire up with an Arduino Uno. The library examples worked out of the box. Good value for the price.

Calibration needed
DHT11 readings were off by a few degrees compared to my thermostat. You get what you pay for. The SHT modules seem better quality based on the packaging.

Good value
The SHT30 is definitely more accurate than the DHT11 version. If you need precision, spend the extra money on the SHT model. Shipping was fast.

Reliable I2C comms
The SHT40 works flawlessly with my ESP32. I2C addressing is straightforward. Readings are stable and consistent over time. Highly recommended for home automation.
Q: What is the main difference between DHT11 and SHT30?
A: The SHT30 offers higher accuracy and faster response times. The DHT11 is more basic and suitable for general hobbyist projects where precision is less critical.
Q: Which library should I use for Arduino?
A: We recommend the Adafruit DHT Sensor Library for DHT11/20 models and the Adafruit SHT31 Library for SHT30/40 models.
Q: Does this work with 5V logic levels?
A: Yes, most modules include a voltage regulator and level shifting, making them compatible with both 3.3V and 5V microcontrollers.
Q: Is the sensor element waterproof?
A: No, the sensor element is exposed. Do not submerge it in water. It can handle high humidity but not direct liquid contact.
Q: Can I daisy chain multiple sensors on one pin?
A: For DHT models, each sensor requires a dedicated data pin. I²C models (SHT30/40) can share the bus if addresses allow, but check specific datasheets.
