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! Features you should know about this sensor: • Operating Voltage: 2.4V min - 5.5V max • 2 factory calibrated sensors for relative humidity temperature 2 • Digital 2-wire interface (Not I C, but similar) • Measurement range: 0-100% RH • Absolute RH accuracy: +/- 2% RH (10…90% RH) • Repeatability RH: +/- 0.1% RH • Temp. accuracy: +/- 0.3°C @ 25°C • Precise dewpoint calculation possible • Fast response time • Low power consumption (typ. 30 µW) • Here’s the datasheet This sensor is ideal for environmental sensing and data logging and can be used in applications ranging from a weather station to a humidor control system.

We recommend soldering four male headers to the breakout board. You can then attach it to an Arduino or Arduino-Compatible Board, such as our RedBoard. Connections: Breakout board to Arduino 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 two data lines. • VCC → 3.3V or 5V • GND → GND • Data → Any I/O Pin • SCK → Any I/O Pin You can connect this sensor directly to the female headers on your Arduino like so… A SHT15 connected to a SparkFun RedBoard, using
