Reliable Sensor
Bought the SHT30 version. Much better accuracy than the old DHT11. Highly recommend for serious projects.

Great for Arduino projects
Works perfectly out of the box. Used it with an ESP32 and the I2C library. Readings are stable.

Works as expected
Simple to integrate. Just make sure you pull-up the data line if using single-wire mode.
