This app has two parts a Logger and Receiver,

The Transmitter will log all data to a .txt file

on drop-box, and the receiver will decode

and display the information.

Also you can view on a PC with your drop-box account,

The app uses the drop-box API from drop-box

and can only write data to a created folder

called Apps.

Notes.

【免費教育App】Sensor link-APP點子

High speed logging <60 seconds will use battery

I found once/hour update no real effect on battery.

This uses your mobile data unless WIFI, so keep

a check as for example once a minute at 2 k file

would be 120 k/Hour 2.8 M byte/week .

【免費教育App】Sensor link-APP點子

This would be fine as most data planes

are 1G(1000Mb)/month.

Also never install on any phone without there

permission! and best to leave status updates

on so you can see when data logged

【免費教育App】Sensor link-APP點子

and file size.

Reference...

Data format on logged file, easy to read into excell.
