Link to software


The GSM module can, among other things, used for:

  • alarms in connection with too high/low water level in e.g. a well or cellar
  • open/close gate or electronic door lock via SMS, call or app.
  • burglar alarm
  • heating/cooling control - switch heating or air conditioning/air conditioning on/off via SMS, call or app.
  • Voltage monitoring - alarms in case of 230VAC failure or low battery.

The module can be programmed via free, included software for PC, or via SMS.

Additional purchases

Remember to purchase an antenna, power supply and possibly a box to keep the equipment in. See the "accessories" tab.
