I am new to MIT Inventor. I'm doing my part final project on automation of water treatment plant. How can i obtain sensor values from Arduino to my app (MIT app inventor). I just want to display the values and maybe store them in a local database later on when i'm familiar with MIT app inventor. I'm using temperature sensor (DS18B30), ph sensor and total dissolved solids sensor. I am using Arduino Uno as my my microcontroller with HC-05 Bluetooth module.
