ClorSensoud documentation

ClorSensoud is a cloud sensor based on the Melexis MLX90614 infrared thermometer which measures sky and sensor temperatures.

How it works

Because clouds reflect ground radiation when present, their temperature difference gives an indication of cloud cover. Sky temperature is cold when clear and close to that of ground when overcast.

The thermometer is controlled by an Arduino board. They are located into a forced ventilated waterproof housing, and linked to a micro-server by a USB cable. The micro-server is in charge of acquiring data and displaying them on a web interface. Data are stored into a SQLite database but last data are also available in plain text files through the network for potential automation.

This documentation covers all aspects of the chain, from the assembly of the measuring instrument to the deployment of the web interface.
