Solid performance

The build quality is decent for the price. I am using the SHT30 variant for a more precise project, and it communicates well over I2C. Shipping was fast.

Perfect for Arduino Projects

These sensors work flawlessly with my Arduino Uno. The DHT22 version provides much better accuracy than the DHT11. Setup was easy using standard libraries.

Bulk buy success

Purchased a lot for our community maker space. All units tested working out of the box. Great for teaching students about environmental sensing.

Good value for monitoring plants

I bought five of these for my automated greenhouse system. They are reliable, though you need to wait a few seconds between readings as specified in the datasheet.

Great starter sensor

As someone new to electronics, this module was very forgiving. The pins are clearly marked, and there are plenty of tutorials online to get started quickly.

Works but requires pull-up resistor

The sensor works fine, but beginners should note that you often need an external pull-up resistor on the data line if your board doesn't have one built-in.

5 FAQ

Q: Can these sensors be used outdoors?

A: While the electronic components can function outdoors, the sensor itself is not waterproof. You must house it in a ventilated, weatherproof enclosure for outdoor use.

Q: Is this compatible with Raspberry Pi GPIO pins?

A: Yes, these sensors are fully compatible with Raspberry Pi. However, ensure you use the correct voltage level (3.3V) and include a pull-up resistor on the data pin.

Q: Which library do you recommend for ESP32?

A: For ESP32, we recommend using the 'DHT sensor library' by Adafruit available in the Arduino IDE Library Manager, which supports both ESP32 and ESP8266 boards.

Q: What is the main difference between the DHT11 and DHT22 included here?

A: The DHT22 (AM2302) offers a wider temperature range (-40 to 80°C) and higher accuracy compared to the DHT11 (0 to 50°C). The DHT22 also has a slower sampling rate.

Q: Do I need to solder the pins myself?

A: The module typically comes with a separate pin header strip. You will need to solder them onto the board yourself unless you purchase a pre-soldered version.
