A GSM controller is a remote control device which can remotely control gates, garage doors and barriers via a mobile phone number. Simply install a SIM card in to the module and then set up the system using SMS messaging from your phone.
Once fully set up, all that is required is to phone the gate to open it.
How does GSM Automation work?
The user calls the number of a SIM card contained within the GSM controller. When the GSM Controller recognizes the number of the caller, it rejects the call and instructs the gate/ door to open or close.
