1c. INTRODUCTION BS-1500GP(R)S TRANSCEIVER

The BS-1500GP(R)S records for each sensor its measurement, GPS position

and time stamp. The measurement data can be transmitted by GPRS (sim

card is necessary) It can also be stored on an SD card (Mico-SD is neces-

sary).

The recorded measurements are also used as input for the internal alarm

control module: It checks the incoming measurements against the given

rules. Depending on the condition given in the rule, an alarm or message is

generated. Rules can be constructed by the rule editor tool, which can be

found in the Multilogger software as well.

When a message is generated, it can be sent to a web service using HTTP via

GPRS. The device also can generate SMS-text messages as alerts.

Furthermore, email messages (using SMTP) can be generated as well. The

text of a message can be customized with data tags like the actual measure-

ment value, sensor id etc.

The BS-1500 usually operates stand alone, but it can also operate as a

BS-510 base station. When connected to the Multilogger software via USB,

the PC will record incoming measurement data via the BS-1500 directly.

The AREXX Multilogger sensors continuously report new values to the

receiver at intervals of about 45 seconds.

Sensors and receiver use a wireless communication system, working at

433MHz. This frequency is freely available for communication at transmitting

powers under 10 milliwatts.

Depending on surrounding building constructions,

the allowed 10mW power level allows a

transmission range of 20-40 meters.

Unreliable signal levels may be improved substantially

byslightlymodifyingthesensor’sorthereceiver’slocation.
