You’ve of a ‘magic eight-ball’ – now prepare to see what magic the number eight is really capable of. With the MyGSM 8I8O GSM module, you’ve got eight outputs to do your bidding.
Multiple input monitoring and activations in a single site for example: 
  • Pump houses (many different pumps); Monitor and control multiple refrigeration units;
  • Use it in a generator room to monitor the power and fluid levels of multiple generators;
  • Perfect for electric fence systems where there are several energisers;
  • Create your own 2G GSM alarm system for monitoring each room in your house by connecting a passive sensor to each of the inputs
…all using a single intelligent device and all via a free missed call or SMS text message from your phone. It doesn’t get much better than that!
In addition, the MyGSM 8I8O offers eight inputs that can be used to monitor up to eight different electrical devices using a single module. Up to 10 users per input can all receive SMS notifications whenever any of the eight inputs are activated; for example when mains power fails, an alarm is triggered, the infrared beams at your gate are interrupted, etc. The functionality of the 8I8O is only limited by your imagination!
