Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: None. We are no longer carrying this board but check out our other evaluation boards in the cellular category. This page is for reference only.

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 to 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 built into the board so there is no need for an antenna. AVR-GSM has 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, take and place phone calls as normal stand alone cellular phone. AVR-GSM can be connected to PC with the USB connector and it is recognized as modem which could be used to add internet via GPRS to your computer.
