The SHT31 sensor could be the finest and highest-accuracy humidity sensor you can find, as it can acquire the relative humidity at only ±2% error. On the other side, it also features excellent performance in terms of temperature measurement, you can use it in some extreme conditions, like -40 degrees or 125 degrees, and it still keeps an accuracy of ±0.3 degrees.

Unlike earlier SHT sensors, this sensor has a true I2C interface, and even with two address options. It also is 3V or 5V compliant, so you can power and communicate with it using just about any microcontroller or microcomputer.
