The AM2315C is a nice, enclosed temperature and humidity sensor that can be powered by anything from 2.5V to 5.5V so it's good with 3V or 5V microcontrollers. You can take sensor readings as often as you like, and it uses standard I2C so it's super easy to use with any Arduino or Linux/Raspberry Pi board.

While it is not rated as 'weatherproof', this sensor would do much better for sensing in weather conditions where there might be wind or rain than SHT PCB-breakout sensors, and the I2C interface makes it easier to interface with microcomputers that can't do the delicate timing of DHT sensors.

This sensor has a typical accuracy of ±2% relative humidity, and ±0.3 °C at 20-80% RH and 20-60 °C. There is only one I2C address so it's not a good option when you need multiple humidity sensors.
