AM2315 Temperature & Humidity Sensor

../../_images/am2315_1.jpg

The flir-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
