TBox20 - GSM Digital Alarm & Control


 

The TBox20 is a low cost solution to Remote Control and Monitoring via your mobile phone. The TBox20 can monitor 2 analogue and 4 digital switch inputs. A SMS alarm message can be sent when inputs exceed preset limits. The user can also interrogate the inputs through SMS messaging. The TBox20 also has 4 relay outputs which can be activated via SMS and used to switch lamps, pumps, heaters etc.

Operation

 

The Tbox20 is an advanced yet simplified Remote Terminal Unit. Taking advantage of the reliable, widespread GSM networks and the supported GPRS service, Tbox20 becomes a remotely accessible unit from any part of the world. Using an embedded feature rich web server interface, you can configure various parameters of Tbox20. The inputs present on Tbox20 can be used for monitoring of external devices or connecting sensors (analogue/digital). Alarm conditions can be configured for monitoring of these inputs. Since Tbox20 supports SMS and SMTP protocols, the device can be configured to send SMS/Email whenever alarm conditions occur. Tbox20 also gives you the freedom to control the states of the connected outputs. By sending a simple SMS you can change/get the status of the outputs.

Given the set of hardware features, software ability and GSM connectivity Tbox20 is an ideal product for use in wide variety of application areas. With minimal to no effort, Tbox20 can be easily integrated in an operational system with ease. Some of the application areas could be (the list is however not limited to these application areas)

  • Security systems

  • Irrigation & fire alarm systems
  • Building surveillance and control
  • Home & garden automation projects
  • Heating, lighting & climate control
  • Remote monitoring and device/equipment control

Wide coverage of GSM networks and the provision of GPRS connectivity have made it possible to interconnect systems wirelessly. Tbox20 exploits the benefits of this wireless technology and gives you control of your remote units from any part of this World. All-in-all Tbox20 is an advanced, effective and an economical solution for fulfilling your needs of remote monitoring and control applications.

 

Functions

 

Remote commands are described by three definitions:

  • event - an occurrence detected by the device, either a state change on one of the four digital inputs, an analogue input exceeding an alarm limit or two types of receiving messages (SMS, call)

  • logic - the relationship between elements
  • action - a state or process that is controlled by the device - a change of relay state (on, off, toggle) or sending a message (SMS, email, call).

With the use of Logics, you can constuct simple sequences, so that more than one action can be taken for an input state. Please see the user manual for more details.

Events

  • Digital High to Low (you can set the de-bounce time 0-1000ms)

  • Digital low to high (you can set the de-bounce time 0-1000ms)
  • analogue input exceeds a limit
  • analogue input falls below a limit
  • user defined SMS message received
  • Call from recognided phone received

Logics

  • AND any event inputs - all events must be true

  • OR any event inputs - any event input must be true

Actions

  • Set output relay high

  • Set output relay low
  • Toggle relay output
  • Send user defined SMS message
  • Call defined phone number
  • Send email (only if service is provided by GSM network provider)
