Raspberry Pi InfluxDB: The solution for IoT Data storage

Raspberry Pi is costeffect linux computer very commonly used for IoT home automation projects.

Here are the 3 problems with conventional databases for IoT data store applications:

• Too much or complex configuration
• Unable to expire data / set retentional policies
• Not tailor made of Time Series Data

var distancePoints = function(p1, p2) {
    // Find the distance between two points
    return Math.sqrt(Math.pow(p2[0] - p1[0], 2) + Math.pow(p2[1] - p1[1], 2));
};

var intersectCircles = function (c1, r1, c2, r2) {
    // Find the points of intersection for two circles
    // Based on: http://stackoverflow.com/a/3349134
    var d = distancePoints(c1, c2);
    if (d > r1 + r2) // Circles do not overlap
