Attention:
Beca
use this is a digital sensor, it takes a little bit more time to measure than an analog sensor. So don’t
set the sample interval of digital sensors too short. 1 second is possible, but probably not ¼ sec. Just to
be sure we choose to sample at the data log interval. Consult the manual of your digital sensor and check
the response time. The sample-interval must be larger than the response time of the sensor.
Next thing is the setup of the data outputs.
Before that, we have to configure the general modem settings for GPRS operation. Consult your GPRS-
provider for the correct local settings. In the reference, a table is included with some international GPRS-
providers and their settings. These settings might have been changed.
Go to Menu-option 2 <Modem settings>
The meaning of this menu-option is to configure the settings of your provider. For the right settings,
please consult your local provider. After this configuration it is advised to check the connectivity of your
device, by using the APN login test. After correct configuring it should look like this:
