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.
