Using an ESP32 as a processor, I developed an integration of components that resulted in my project: checking and monitoring the water tank level in real-time. 

This system is associated with a flow sensor that monitors the amount of water entering the tank, allowing comparisons with the home's water meter.

Flow Monitor Sensor

The device has Wi-Fi or GSM access, ideal for tops of buildings where there is no network infrastructure. In addition, it has remote pump triggers, integration with Alexa, and a complete app with graphs and water flow measurements.

I developed a printed circuit board to organize and reduce system failures. The project operates with a voltage of 9V and has a device configuration screen for Wi-Fi adjustments and other parameters.

Installation is very simple: an ultrasonic sensor is fixed to the top of the box lid and connected to our device.

A SKILL was developed for Alexa where she asks a simple question about the status of the box level at scheduled times.

The ultrasonic sensor support was also developed in the 3d printer, where we achieved a better inclination angle that avoids condensation droplets.
