This application note demonstrates how to make a simple system that monitors temperature and analog voltages remotely. On meeting certain alarm conditions, the system can send SMS messages, which are then converted to E-mail and forwarded to the designated E-mail address.

System Components:

1. PIC® microcontroller (PIC 16F877)

2. 1-Wire® temperature sensor (DS18S20)

3. 8-channel 12-bit, serial A/D converter (MAX127)

4. GSM modem

5. SMS to E-mail conversion service provided by TynTec
