Hello Everybody,
Expert advise required on GSM/GPRS connection;
I want to send/receive data to/from a balloon carrying some sensor. Initially balloon will be tight to a rope and will rise gradually in human control. It will send altitude, temperature, humidity, windspeed, GPS data via GSM/GPRS module to a control computer and to a mobile phone on the ground. It will also receive some remote control commands through the same communication channel.
- How high the balloon can rise before GSM/GPRS signal vanishes? - Is there a legal altitude limit for GSM/GPRS operation? - Which GSM/GPRS modules you would recommend for the balloon and for the computer (please consider the price and locality as Australia)? - Do you know any similar project or any open project which can help me to learn more on GSM/GPRS data communication?
Thank you
Albert
