SparkFun Humidity and Temperature Sensor Breakout - SHT15

Description

This board has been fully calibrated and offers high precision and excellent long-term stability at a 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 strong resistance to external disturbances. Additionally, the onboard SHT15 features a 0-100% RH measurement range with a temperature accuracy of +/- 0.3^oC @ 25^oC. 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.
