Discontinued - you can grab AM2315C - Encased I2C Temperature/Humidity Sensor instead!
5V power input. Adafruit product page states: connect the red wire to 5V power. Pullups for SDA/SCL connect to this power wire.
Ground. Adafruit product page states: black to ground.
I2C data line. Adafruit product page states: yellow wire to your i2c data pin; SDA/SCL require about 10K pullups to the power wire.
I2C clock line. Adafruit product page states: white wire to the i2c clock pin; SDA/SCL require about 10K pullups to the power wire.
