Short Description

TCG120 is a micro-controller based device for GSM-GPRS temperature monitoring and control over mobile networks. It has 2 digital inputs, 2 analog inputs, 1-Wire interface for up to 4 Teracom humidity and temperature sensors. Its 2 relays has normally open and normally close contacts.

The relays can be activated either remotely (via SMS or HTTP API command) or locally – from status of monitored parameter. Only one parameter can manage the relay at the same time, but for every parameter can be sent e-mail or SMS for alert conditions.

The controller can be used as standalone device or as a part of data acquisition (SCADA) systems. TCG120 may periodically send data to a remote server, which makes it suitable for use in client-server systems for GSM-GPRS temperature monitoring and control.

Features :- 

  • Quad-bands GSM connectivity;
  • Setup via USB (Windows setup program) or SMS;
  • 2 digital inputs with ” dry contact” and “logic level” modes;
  • 2 analog input with 0 to 60VDC range;
  • 2 relay output with NO and NC contacts;
  • Long 1-Wire support for up to 4 Teracom TSTxxx (temperature) and TSHxxx (temperature&humidity) sensors;
  • SMS alarm alerts (up to 5 numbers);
  • Email alarm alerts (up to 5 email recipients), SMTP with SSL support;
  • Single call control – the relays can be controlled with a single call from up to 100 numbers;
  • Push mode – XML data is sent via HTTP post method to remote server;
  • HTTP API commands;
  • Firmware update over USB or GPRS.


Typical Applications :- 

TCG120 is an universal device and can be used in various aplications such as:

Remote environmental monitoring and control for homes, offices, server rooms etc;

  • Temperature and humidity control;
  • Remote control of electric devices;
  • Home and office alarm systems;
  • Industrial process automation;
  • Control and management of large networks.
