Significant upgrade over DHT11
The I2C interface makes wiring much cleaner compared to the single-wire protocol of the DHT11. Readings are stable and respond quickly to changes in room humidity.

Easy to integrate
Found plenty of libraries for ESP32 and Arduino. The code examples worked out of the box. Much more precise than the blue DHT11 I used previously.

Good value for money
Solid performance for the price point. The only reason for 4 stars is that the pinout diagram on the module itself is a bit small to read without a magnifier.

Reliable and fast
Using this in a weather station project. The response time is impressive, and the data consistency over the last month has been excellent.

Perfect for my plant monitor
I replaced three old sensors with these DHT20 modules. The accuracy is noticeably better, especially in the lower humidity ranges which matters for my setup.

Great sensor, check your pull-ups
Works flawlessly once I added the correct external pull-up resistors for the I2C lines. Make sure your microcontroller supports the address correctly.
Q: How does the power consumption compare to DHT11?
A: The DHT20 is generally more power-efficient, especially in sleep mode, making it a better choice for battery-powered projects.
Q: What is the I2C address for this sensor?
A: The default I2C address for the DHT20 is typically 0x38. Please refer to the datasheet if you need to verify specific batch configurations.
Q: Does it come with header pins soldered?
A: No, this module is shipped with unsoldered header pins to allow for flexible mounting options. You will need to solder them yourself.
Q: Is this module compatible with 3.3V logic levels?
A: Yes, the DHT20 operates from 1.8V to 5.5V, making it fully compatible with both 3.3V and 5V microcontrollers like ESP32 and Arduino.
Q: Can I use this outdoors directly?
A: While the sensor element is robust, the breakout board itself is not waterproof. We recommend placing it inside a ventilated, weatherproof enclosure for outdoor use.
