Solar-Weather-Station

DEAD PROJECT - GO HERE INSTEAD: https://github.com/BuckarewBanzai/Storm-Cloud

A web front end for my solar powered weather station. Built on Apache wsgi, sqlite3, PHP, and python. Capable of detecting lightning strikes but more features to come. With the current power setup the station can run for 3 days of overcast. Moving the web server and databse off the pi could improve power consumption.

Database Schema (NEW):

CREATE TABLE nodes(nodeid TEXT, latitude NUMERIC, longitude NUMERIC, status NUMERIC, dateadded DATE);
		
CREATE TABLE strikes(nodeid TEXT, date DATE, distance NUMERIC);

CREATE TABLE power(nodeid TEXT, date DATE, volts NUMERIC, amps NUMERIC, watts NUMERIC);

CREATE TABLE multisensor(nodeid TEXT, date DATE, humidity NUMERIC, pressure NUMERIC, temperature NUMERIC);

Tiny API

Implemented a small api in flask and apache wsgi. Goals are to allow multiple weather stations to communicate with one server allowing station monitoring, lightning triangulation, and weather modeling.

API Endpoint Resources:

/nodes
	GET - List nodes, locations, and status (online/offline)
	POST - Add new nodes to the system

/nodes/{nodeid}
	GET - Get information on single node
	PUT - Modify information on a single node
	DELETE - Delete node but not node data
	
/nodes/{nodeid}/strikes
	GET - List all strikes for {nodeid}
	POST - Write single strike distance and date/time
	
/nodes/{nodeid}/power
	GET - List all power data for {nodeid}
	POST - Write new power data 
	
/nodes/{nodeid}/multisensor
	GET - List all multisensor data for {nodeid}
	POST - Write new sensor data
