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.

you can readily use ESP32 for your WiFi and BLE tasks, though ultrasonic sensor is not that power efficient typical example of that sensor HC-SR04 pulling around 15mA, while lidar based one ie: vl53l0x pulls around 6mA ESP32 won't really run on coin cell ( these cells have much higher internal resistance) , 3.7V LiPo battery will do ESP32 can work in sleep modes to save battery power
