Opinionated comments on mobile phone industry news

By sending a specially formatted SMS (8 1s or 0s) to a mobile phone with this SMS Remote Control you can set up to 8 relays on/off.

Any phone will do (at least in theory), as the add-on board uses standard AT sequences to read out the SMSs.

The longer chip shown on the board is actually an Atmel AT90S2313 single-chip MPU (CPU with memory), so part of the solution is to load this MPU with a small application that reads out the SMSs from the phone.

The note also gives advice for if you want to read out SMSs using a PC. You could potentially also send SMSs this way, e.g. for sending alarms, statistics etc from equipment.

You could similarly create a request/response service for low-traffic SMS communication where you pay for the outgoing SMSs, using a phone, a PC and the Kannel WAP/SMS Gateway, and of course also some programming skills.

Of course, for professional applications you should get mobile modules instead, like these from Telit where some can be programmed via the Python language.
