Schematic, Layout Design - Microcontroller Firmware - BLE+WiFi

What we seek is that a small gadget, I will provide sizes later on, which has an ultrasonic sensor and checks the liquid level of a tank and sends the data by connecting to the internet via Wi-Fi to a specific web server.

The project comprises 2 parts.

1st part is electronic component selection, schematic design, and simple layout. -----There should be one button for on/off and Bluetooth synchronization.

-Battery-powered, preferred 3V coin cell battery.

-Ultrasonic sensor range is between 0.05 to 2 meters.

-I will provide websites for component selection.

2nd part is firmware based on chosen micro-controller.

-On/Off by pressing the button for 5 seconds.

-Bluetooth will be activated only for a minute after pushing the button 5 times.

-We will use Bluetooth only for sending SSID and Password of the Wi-Fi that gadget will connect.

-Implement a simple GATT protocol

-Create a simple minimalistic iOS and Android to show working communication

-After the device connecting to Wi-Fi, it will send the liquid level of the tank once an hour with the id of the device and time.

I'm expecting a calculation of battery life.
