GSM Remote Control Switch

The GSM-AUTO is a GSM remote control switch, it connects to the mobile phone network and like a mobile phone has its own telephone number. The GSM-AUTO is activated by calling its phone number, it will recognise an authorised telephone number calling it, reject the call without answering and switch on or off the device connected to it, because it rejects the call without answering there are no call costs incurred.

It has 2 independent relay switches, these can be programmed to switch on for a pre-determined length of time whenever the GSM-AUTO is called.

The relay switches can also be temporarily or permanently switched on or off by sending the GSM-AUTO a sms text message command. It can report the relay status by sending a text message.

Applications include GSM control of heating, lighting, engine pre-heaters, aviation engine pre-heaters, irrigation systems, water well pumps, pumping stations, remote access control of gates , re-setting of remote servers and routers, control of remote scientific instruments.
