This is how it works:
A microprocessor is monitoring connected sensors. Data collected from sensors are sent to a webserver through a wireless GSM-modem.

Alarms can be defined with SMS-messages. If an alarm-situation occurs, a message will be sent to the webserver. Furthermore, a SMS-message can be sent.

Each user has a web-site, showing status for each installation.

The values are normally updated everry halv hour, but it can be done more often if required.

Each controller can monitor several sensors.

All kinds of signals can be monitored, 0 - 10V / 4 - 20mAmp signals or pulse signals. Other units can be controlled, f.ex. start / stop of motors.
