ZigSense model ZS3G-SMS GSM/3G monitor and control node

The ZigSense model ZS3G-SMS is an out-of-the-box monitor and control node utilising standard GSM/3G cellular networks as its communications infrastructure to exchange SMS messages.

By sending SMS commands to the ZS3G-SMS cellular node, authorised users can remotely monitor and control up to four digital inputs and four digital outputs wired to a wide range of industrial equipment, remote irrigation systems, motors, pumps, generators, fans, lighting systems and PLCs.

Using a standard mobile or smart phone, authorised users enter commands selected from a list of preprogrammed SMS messages. These commands are sent to cellular phone numbers predefined by the user.

For every command sent by the user, the ZS3G-SMS cellular node returns an SMS acknowledgement message advising the sender whether the command was successfully accomplished.

To maintain safety and security, the ZS3G-SMS cellular node constantly checks that the message was sent by an authorised cellular phone number and that the SMS message matches the syntax programmed in the cellular node’s non-volatile memory. Erroneous SMS message syntax or commands sent by unauthorised users will be rejected. Rejection messages are sent to the sender and to the administrator.
