Based on the ETM9xxx-1 range of Intelligent cellular modems these units can monitor temperature and/or other variables and send an SMS alarm when conditions go outside range.
Both the 2G GSM and 3G/NextG models function in the same way and use the same configuration tool, however the ETM9910-1 3G/NextG model benefits from the better coverage of 3G networks and makes it ideal for demanding rural and regional applications.
When operating as temperature alarms these units will allow for:
- Checking temperature conditions from your phone using SMS
- Sending SMS alarms
- Connection of other variables such as pressure sensors, digital inputs (such as alarm outputs from HVAC equipment) and switching of outputs to turn a piece of equipment ON/OFF or to reset it
In addition to SMS alarm the units can be configured to send data to a logging service (ekoCALM) which will keep a log of conditions and allow for sending of email alarms if required. All logged data can be accessed online via a web interface and downloaded for further analysis.
