GitHub repository: KalifiaBillal/Water-Level-Monitor-Using-Arduino-Firebase-And-Android-App
Description: The project uses arduino uno equipped with ultrasonic sensor to measure water level and sends notification to an android app. The notification is done through firebase cloud messaging. However arduino cannot send data directly to firebase so a php page is used to accomplish it. The Android App is built to receive firebase notification and also to place orders. The order details are saved in firebase database.
