Perfect for my plant monitor
Accuracy is noticeable compared to cheaper sensors. Running it on an ESP32 without any issues so far.

Good sensor, tricky library
Sensor works well but needed to find the right library for the I²C address. Once configured, it is solid.

Great upgrade from DHT11
Much more stable readings than the old DHT11. The I²C interface makes wiring much cleaner on my breadboard.

Consistent data logging
No more random spikes in humidity data. Very happy with this upgrade for my home automation system.
Q: What is the default I²C address?
A: The default I²C address for the DHT20 is typically 0x38.
Q: Is this compatible with Arduino Uno?
A: Yes, it works with Arduino Uno using the standard I²C pins (SDA and SCL).
Q: Can I use this sensor outdoors?
A: It is not waterproof. Please use a protective enclosure if deploying outdoors.
Q: What is the difference between DHT20 and DHT22?
A: DHT20 is newer with an I²C interface, while DHT22 uses a single-wire digital output.
Q: Does it come with header pins?
A: Yes, the module includes pre-soldered headers for easy breadboard use.
