AM2315 - ENCASED I2C TEMPERATURE/HUMIDITY SENSOR

The AM2315 is a digital I2C humidity - temperature sensor that is mounted in a protective housing. It is not waterproof but sufficient to provide some protection to both sensors mounted inside. It use the DS18B20 along with a capacitive humidity sensor. It has it's own controller that provides a I2C interface to both of these sensors. We cannot change the address of device so it only supports one device per I2C bus. It is supplied with two mounting brackets depending on how you want to physically mount the device.

Simply connect the red wire to 5V power, black to ground, yellow wire to your i2c data pin, and the white wire to the i2c clock pin. You cannot change the i2c address so only one sensor per i2c bus. Two ~10Kohm pullup resistors are required for use, connect from the SDA and SCL lines to the power wire, the pullup resistors are not included!
