User manual BS1000 LAN base station 15 / 18 July 5 2010
Variable Description
$v Measured value
$q Sensor type 1 = Temperature (°C), 3 = RV% (%), 5=CO2 (ppm)
$i Identification number of the sensor
$r rssi-value (signal level value in dBm)
$h Indication of the hours in the time indication of the measurement
$m Indication of the minutes in the time indication of the measurement
$s Indication of the seconds in the time indication of the measurement
$Y Indication of the year in the time indication of the measurement
$M Indication of the month in the time indication of the measurement
$D Indication of the day in the time indication of the measurement
$S Measurement time in seconds since 1-1-2000 UTC
$w Missing; Time when the latest measured value has not been transmitted to
the http server. Is required for the update of the temp-logger.
$t time string; Time of measurement in the format: hh:mm:ss
$d datum string; Date of the measurement in the short date format
Except for the $w and $S, all time indications are expressed in UTC under consideration
of the time zone offset indication in the config page screen Time server.
The time indications $w and $S are expressed in UTC.
The HTTP request message is base64 encoded. This means that non-alphanumerical
characters are converted into %hh-strings where „hh“ represents a hexadecimal figure.
The lines '&&' and '==' are an exception: these are converted into '&', and '='
respectively. The message for the HTTP request is transmitted via the request header
POST, or else added to the URL of the GET request. In this case, the separating sign '?' is
added between the URL and the message.
Example of a message:
id==$i&&value==$v
In this example, a web server is programmed to decode the indicated string in two
parameters 'id' and 'value'. This method allows to supply up-to-date data from the BS1000
to a web page without a running a PC.
This method is also used for the update of the Temperature Logger.
Buzzer
The buzzer is activated as soon as the condition has reached the value “true”. The buzzer
is shut off automatically after 5 minutes. You can also switch off the buzzer by pressing
the button on the rear panel of the BS1000.
Flashed data
A special xml page is implemented to let other software retrieve data from the BS1000.
The page data.xml outputs flashed data within a given period.
