1c. INTRODUCTION BS510 WIFI TRANSCEIVER

The BS-510records for each wireless sensor its measurement and time stamp.

These measurements are shown in the Multilogger software.

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

software which is also installed on your PC with the logger software. It checks

the incoming measurements against the given rules. Depending on the condi-

tion given in the rule, an alarm or message is generated. Rules can be con-

structed by the rule editor tool, which can be found in the Multilogger software

as well.

When a message is generated, the PC can sent it to a web service using TCP/

IP protocol via the WIFI/LAN network. The PC also can generate e-mail mes-

sages as alerts. Furthermore, email to SMS text messages can be genera-

ted as well. The exact action depends on the rules dened and stored in the

PC. The text of a message can be customized with data tags like the actual

measurement value, sensor id etc.

The BS-510 usually operates connected to a PC but it can also operate as

a stand alone base station. When connected to the Multilogger software via

USB, the PC will record incoming measurement data on the PS harddisk

directly.

The AREXX Multilogger sensors continuously report wireless new values to the

receiver at intervals of about 45 seconds. This time is xed in the sensors

and cannot be changed.

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.
