#FreeDavis project This project aims to provide a user-installable, idiot-proof and reliable way of accessing data provided by the instruments made by a company called Davis. The outdoor units are pretty accurate and reliable units, but to be honest, the inability to access / dump / mine / connect to the data directly, is a limiting factor.
##Desired functionality As the name suggests, the whole thing should be an open system, based on open software. From the things that the system should be capable of:
- receiving the data from outdoor sensors (obviously)
- Logging and storing the data
- Display / analysis / plotting
- Possibly sending of data
##Data receiver Data receiver part is accomplished by a CC1101 wireless chip connected to an Arduino mini, both working on 3.3V. Dtat is being sent via serial Rx Tx pins of the arduino.
##Data logger Current working solution incorporates an additional connection of a RaspberryPi that loggs data sent by the Arduino via serial interface.
- data extraction written in python
- data feeder written in python (influxDB connector)
- data logging and storing is accomplished via InfluxDB (subject to change?)
- data serving python app based on cherrypy
- UI based on bootstrap3
- graphing by Dygraphs.js
Hardware used:
Arduino mini pro 3.3V
RaspberryPi (any version basically)
some wiring together (todo: picture of wiring in svg)
