PIC Thermostat controlled by SMS - Final assignment
I didn’t succeed in getting the SMS communication to work. The compiler had various problems, and due to the time constraints we decided to simplify the task.
When a text-message with the word “Temperature” arrives on the Wavecom modem, the sender received an SMS with the current temperature.
Below are some pictures of the setup with the DB038 PIC board and the Wavecom modem (and RS232 to TTL conversion). On the photographs, the setup is connected to a computer for debugging purposes, it can also operate stand-alone. It is a completely embedded system.
