Description: AVR-GSM is excellent board for adding remote monitoring and control in remote places by GSM cellular network. Do you want to switch on/off your local heating in your mountain house? To monitor the temperature at up to 8 remote points up to 30 meters away from the module? To listen what happens in your house with silent call after you get message for alarm status? Then AVR-GSM is the board for you! It contains ATmega32 microcontroller and 3-band GSM GPRS module 900/1800/1900Mhz inside which covers most used GSM networks around the world. The GSM antenna is build in the board so no need for external expensive GSM antennas.

Description: Hello guys,
I ve built this GSM security system as my semester project using T290i mobile and controlled my car using it. Please leave your comments about it.
If any one needs help in implementing such a system, I can help.
Some of the functions it can perform are:
* start and stop the engine (without using the key)
* stop the engine if somebody starts it with a key ( by cutting off ignition)
* lock and unlock the doors
* send a text message to the owner if an intruder is detected (by monitoring the doors)
* switch the heater/air conditioner on and off
