For a project I and my teammates want to make a fully working prototype using an arduino microcontroller.
The system needs to be able to: - operate completely standalone. - measure input from up to 4 (probably all analog) sensors. - work for a complete hour or more.
The data will consist of values from the sensors that need to be saved each second for example.
To be able to read the data of our sensors we want to either: - store data gathered from the sensors on the standalone system. - send data gathered from the sensors wirelessly to a computer.
To send data wirelessly, we thought of these solutions: - Bluetooth - ArduinoXbeeShield (Zigbee)
Our question is: what kind of solution do you suggest? Are there any other solutions that we haven't mentioned? If you want to know more details, please ask. Thanks in advance!
