SparkFun Humidity and Temperature Sensor Breakout - SHT15

The SHT15 Breakout is an easy to use highly accurate digital temperature and humidity sensor. This board has been fully calibrated and offers high precision and excellent long-term stability at low cost. The digital CMOSens® technology integrates two sensors and readout circuitry on one single chip. All you need is two lines for 2-wire communication and you’ll have relative humidity and temperature readings to help you sense the world around you!The two sensors built into the SHT15 have been seamlessly coupled to a 14bit analog to digital converter and a serial interface circuit resulting in superior signal quality fast response time and a strong resistance to external disturbances. Additionally the on board SHT15 features a 0-100% RH measurement range with a temperature accuracy of +/- 0.3°C @ 25°C. There are only four pins that need to be hooked up in order to start using this sensor in a project. One for VCC one for GND and the two data lines SDA and SCL.
