Application Ideas
- M2M (Machine 2 Machine) Application – To transfer control data using SMS or GPRS between two machines located at two different factories.
- Remote control of appliances – Send SMS while you are at your office to turn on or off your washing machine at home.
- Remote Weather station or a Wireless Sensor Network – Make it with [Crowduino v1.0|Crowduino v1.0] and create a sensor node capable of transferring sensor data (like from a weather station – temperature, humidity, etc.) to a web server
- Vehicle Tracking System – Install GPRS+GSM+GPS Shield in your car and publish your location live on the internet. Can be used as an automotive burglar alarm.
Cautions
- Make sure your SIM card is unlocked.
- The product is provided as is without an insulating enclosure. Please observe ESD precautions especially in dry (low humidity) weather.
- The factory default setting for the GPRS Shield UART is autoloading. It supports baud rate from 1200 bps to 115200bps. (Can be changed using AT commands).
