I recently discovered the AOSONG AM2315 humidity/temperature sensor and was quite intrigued. This is a very accurate and affordable device that is a nice addition to a current project. Supposedly, this device is i2c compliant, so I figured it would be easy to talk to. Little did I know….
After hacking around for a couple of long days I was able to get the device working on my breadboard with a Pi Cobbler. Google and forum searches determined there are a lot of people struggling to get the device to work….

AM2315 – Encased I2C Temperature/Humidity Sensor: Finally we have an I2C-interface temperature & humidity sensor in a nice enclosed style. This sensor contains a DS18B20 temperature sensor and a capacitive humidity sensor. A small microcontroller inside does the readings and provides a simple I2C interface for reading the finished & calibrated output data. Especially nice is that this sensor is in a rugged case with mounting bracket, which makes it way superior to a normal PCB-mounted sensor. While it is not rated as ‘weatherproof’, this sensor would do much better for sensing where there might be wind, rain, zombies, etc. than SHT PCB-breakout sensors, and the i2c interface makes it easier to interface with microcomputers that can’t do the delicate timing of the DHT sensors.
