Hi everybody!
I'm new in electronics, so my questions can be strange but I have to ask.
I need to continuously send information from sensor to smartphone via Bluetooth.
1. I heard that if I take HC-05 BT module, then I can do without microcontroller. Is it true? If yes, tell me how to send the information without it. If no, which microcontroller would you recommend? It would be great if it is small and not expensive.
2. Can I receive this information and dispose it in app written in MIT App Inventor 2?
3. Can I turn on and off the sensor remotely? How to do it, if it's possible?
Thanks in advance)
