How can I let Arduino send message or alert to my phone? (HC05)

Using Arduino Project Guidance

Hey guys so im working on a water dispenser project and ive installed a water level sensor as well. So I want the Arduino to alert or notify me whenever it detects that the water level is low or that the tank is empty. I want it alert my phone by using the HC05 blue tooth module. Thanks

Have you been able to pair the HC05 with your phone? Can you connect the HC05 with an app like Serial Bluetooth Terminal and send and receive data.

There are examples on YouTube.

Do not cross post. Reported.

Please provide more detail.

Which OS on your phone?
Where are you stuck? Arduino side or phone side? Or both?

Did you already try to get communication going? For Android, there are BlueTooth terminal programs that you can use for testing; not sure if they exist for other operating systems.

Which Arduino are you using? For boards with a single serial port (e.g. Uno, Nano, ProMini) you probably want to use software serial during development; you can later change to hardware serial if required.

I submit you should think about this again. It is a seriously dumb idea, but you can salvage it if you ditch Bluetooth and use a phone module instead . If you insist on using Bluetooth, you are in the wrong place anyway, it is an Android problem. There may even be a solution there already, but I'm not aware of it.

1.) BT wont give you very much range to get this info...

2.) You would have to run an app and be connected ta all times.

3.) Still no OS reported? But if Android based (not sure why mention of it being an 'Android' problem?) you can perhaps look into using MIT APP Inventor (been a while since I played with it).. but was easy enough to make some apps for Android based phones.

I was just being charitable. Since OP wants to use HC-05, you wouldn't want this to be an IOS problem. As things are, getting an alert out from Arduino can hardly be a problem at all, but what you do with it at the Android end is a serious problem, and I submit doing it via HC-05 doesn't merit consideration.
