Hey guys first time poster here
I have an android app that can read one sensor value from the arduino which is sent over a BT module.
I was wondering how i could be able to send multiple sensor values to an android app.
My thoughts were on inputting data into an array on the arduino and sending it to the phone thru BT.
Any other suggestions or how i may be able to implement this?
Thanks! 
You will probably find that your Android app can read a swag of sensors, it is just a matter of sending the data properly. You send the readings to Android the same way as you send them to the serial monitor, and about all you need change might be the spacing.
With Bluetooth Graphics Terminal, you can display up to three values on a graph.
