InfluxClient

InfluxClient is a tiny client for writing simple data points to and from the InfluxDB 1.x REST-API.

installation

Clone the repository to the library directory inside your Arduino directory, often located at ~/Arduino/libraries/.

InfluxClient depends on the Arduino http client. The http client can be installed using the Arduino IDE.

using

Create an instance of the class Influx by providing the server url, the database name and the measurement.

#include <InfluxClient.h>

Influx flux("http://192.0.2.254:8086","sensordb", "measurement");

writing

Set the tag for your data point you want to write to the server.

flux.setTag("location", "attic");

Send one or more data points in a single http-request to the database:

void sendMeasurements(float sensorValues[]) {

    DataPoint dataPoints[MEASUREMENTS];

    for (int m = 0 ; m < MEASUREMENTS ; m++ ) {
        dataPoints[m].field = getFieldString(m);
        dataPoints[m].value = sensorValues[m];          
    }

    // sending all sensor values in one http request to InfluxDB
    flux.sendMeasurement(dataPoints, MEASUREMENTS);
}
