AM2315 Temperature & Humidity Sensor¶
The foglamp-south-am2315 is a south plugin for a temperature and humidity sensor. The sensor connects via the I2C bus and can provide temperature data in the range -40oC to +125oC with an accuracy of 0.1oC.
The plugin will produce a single asset that has two data points; temperature and humidity.
Note
The AM2315 is only available on the Raspberry Pi as it requires an I2C bus connection
To create a south service with the AM2315 plugin
Click on South in the left hand menu bar
Select am2315 from the plugin list
Name your service and click Next

Asset Name: The name of the asset that will be created. To help when multiple AM2315 sensors are used a %M may be added to the asset name. This will be replaced with the I2C address of the sensor.
I2C Address: The I2C address of the sensor, this allows multiple sensors to be added to the same I2C bus.
