Sen saphone WSG-30 Wireless Gateway Sensor System Monitor, Stand Alone or with Industrial Automation System

S ensaphone WSG30 sen ds e mail notifications, tex t messages or  communicates directly with existing HMI (Human Machine Interface) software using the Modbus protocol. Monitors up to 30 sensors

In stand alone system use:
Monitors conditions from wireless sensors: the WSG30 directly notifi es   appropriate personnel by sending e-mails and text messages. For example, w ireless se nsors monitoring of heat problems within a data cent er, monitoring refrigerator and freezer temperatures and use medi cal appli cations where running wire would be in convenient or costly.

ithin an existing indu strial automation system: 
The WSG30 can communicate directly with existing HMI software using the Modbus protocol. Sensor and transducer values can be sent wirelessly to the WSG30 main unit and then directly into your automation software. Beside supplying live wireless sensor information to your existing automation software, the WSG30 can also independently send e-mail and text message alarm notifications at the same time.

The Sensaphone WSG30 can monitor u p to 30 wireless sensors i n addition to the automatic power failure alarm detection and diagnostic alarms. All sensors are supervised with their battery level reported and monitored. Monitors up to 30 sensors as far away as 300 feet plus automatic power failure alarm detection and diagnostic alarms.

If any sensor has a low battery or drops offline, a diagnostic alarm is generated and users are contacted. A rechargeable battery backup is also built in.

  • Up to 30 wireless sensors can be monitored by the WSG-30 in addition to automatic power failure alarm detection and diagnostic alarms.
  • Sensors can be up to 300 feet away.
  • Creates its own Mesh Network so that sensors can be used as repeaters and routers.
  • The Wireless sensors can operate on standard AA batteries for up to 3 years.
  • If any sensor has a low battery or drops offline, a diagnostic alarm is generated and users are contacted.
  • All sensors are supervised with their battery level reported and monitored.


  • Wireless Sensors
  • Alarms
  • Interfacing
  • Data Logging

Alarm Notification:

  • Eight User Profiles can be programmed with 4 Contact Methods for each one, for a total of 32 alarm notifications.
  • Each Contact Method can be an email or a text message.
  • When used in a data center environment, alarms can also be sent directly to Network Management Software using SNMP traps.

Alarm Scheduling and Selection:

  • Each sensor can be programmed with a schedule so that it is only monitored for alarms when you need it.
  • Even the alarm delivery to the users can be scheduled so that different people are notified for alarms depending on time of day and day of the week.
  • In addition to the flexible scheduling options, there is also the ability to have different people notified for different alarms. So, only the people responsible for a particular issue will be the ones who are notified.

Built In Alarms:

  • The WSG-30 comes with some built in alarms: Power Failure, Low Backup Battery, and Sensor Diagnostics for low sensor battery or sensor not responding.

Battery Backup:

  • The WSG-30 main unit has an internal battery backup system to power the device for up to two hours if power fails.
  • The WSG-30 includes a built-in web server. Browse to its web page for all programming, configuration, and access to current status. Even alarm history and data logging can be easily accessed through the web. Up to 64,000 time stamped records can be stored inside the WSG-30 to follow history and trends of the monitored conditions. Data log history can be accessed directly through the built in web page, exported in a standard format, or interfaced using XML.

Local Display:

  • For a quick local check of the sensors, there is a 4 line display and keypad interface right on the front. The status of all sensors can be easily and quickly viewed at anytime without the need for a computer.

Modbus Protocol:

  • Support for the Modbus protocol is included in the WSG-30. Third party automation software can be used to connect and pull data for all sensor values in real time.

SNMP Management:

  • The WSG-30 also allows full remote management using the SNMP protocol. All status values as well as programming parameters can be accessed using Get and Set commands from standard network management software.
