Easy to integrate
Found plenty of libraries for Arduino and Python that support this out of the box. The documentation is clear, and the module arrived well-packaged.

Great sensor, needs pull-up resistors
Works flawlessly with my ESP32. Just remember that you need external pull-up resistors on the SDA and SCL lines if your board doesn't have them built-in. Once set up, it's rock solid.

Solid upgrade
Good precision for consumer-grade electronics. It handles condensation better than the DHT11 did in my bathroom exhaust project. Would buy again.

Much better than the old DHT11
The I2C interface makes wiring so much cleaner compared to the single-wire protocol of the DHT11. Readings are stable and fast. Highly recommended for any new IoT project.

Fast response time
The response time is significantly faster than previous generations. I can log data every second without worrying about stale readings. Excellent value for the price.

Perfect for my plant monitor
I replaced all my old sensors with these DHT20 modules. The accuracy improvement is noticeable, especially in high humidity conditions. No more erratic spikes in data.
Q: What is the default I2C address?
A: The default I2C address for the DHT20 is typically 0x38. However, please refer to the specific datasheet of your manufacturer as some variations might exist.
Q: How often can I poll data from this sensor?
A: The sensor has a conversion time of less than 2 seconds. We recommend polling no faster than once every 2 seconds to ensure accurate readings and prevent bus locking.
Q: Is this module compatible with 5V Arduino boards?
A: Yes, but since the operating voltage is 1.8V-3.6V, you should use a logic level shifter or a breakout board with a voltage regulator when connecting to a 5V system to avoid damage.
Q: Can I use this outdoors directly?
A: The sensor chip itself is not waterproof. You must house it in a weatherproof enclosure with a breathable membrane to protect it from rain and direct water exposure while allowing air flow.
Q: Does it come with header pins soldered?
A: This item is sold as an integrated digital module. Most versions come with header pins pre-soldered, but please check the product images for the specific batch you are ordering.
