INFO:
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. AVR-GSM
have two relays 240VAC/10A, two optoisolated inputs which could be connected
to alarm sensors or just buttons for user actions (like call pre-loaded phone
numbers), on-board temperature sensor and connector for additional up to 8 addressable
remote temperature sensors at up to 30 meter distance from the module. Normal
phone hook can be connected to this board and to allow user to speak, listen,
taking and placing phone calls as normal stand alone cellular phone. AVR-GSM
can be connected to PC with the USB connector it have and it is recognized as
modem which could be used to add internet via GPRS to your computer (imagine
how useful is this for your mountain house if there is no internet but only
cellular network!).
