LOBOViz CGI Data Service

The LOBOViz server has a public CGI (Common Gateway Interface) that allows remote clients to request and receive LOBO sensor data via HTTP (Hyper-Text Transfer Protocol). This page describes how to access the CGI and retrieve sensor data.


The LOBOViz data CGI for this server is published at the following URL:


CGI Data Query Parameters

Parameters are appended to the URL after a '?' character and are each is subsequently separated by a '&' character.

The following common parameters are supported:

min_datefirst day of data query in format [YYYYMMDD]
max_datelast day of data query in format [YYYYMMDD]
ycomma-separated list of measurement names for dependent variable(s)
data_formatrequired to be 'text' for text output

Rather than specific min_date and max_date, there are two alternate date selectors:

days=nthe most recent n days from today
newest=nthe most recent n measurements

The following common measurement names are examples of the 'y=' independent variable list:

cdomcolored dissolved organic matter
oxygendissolved oxygen
nitratenitrate concentration
oxygen_satoxygen saturation
voltagepower supply voltage
scatteringscattering coeff
temperaturewater temperature

CGI Data Result Format

The data are returned as tab-separated text representations of numeric values. The first line of the returned data is a header of tab separated names and units for each data column. Each subsequent line displays local date/time in format [YYYY-MM-DD hh:mm:ss], followed by a numeric value for each requested measurement, all fields separated by tabs.


For example, if you want to retrieve nitrate and salinity for September 29, 2008 to October 7, 2008 the URL would be:,salinity&data_format=text

Click the above URL to see the tab-separated text data returned by the server. That is common example: exact identifiers for sites and sensors can be found by using the PermaLink feature on the graph results page.

Scripted Usage

Any programming language with HTTP support can be used to directly access the LOBO data CGI and process the returned sensor measurements. Alternately, an HTTP utility such as wget can be invoked to retrieve the data and save to local file for later processing.
