Prototype

In Argentina, access to safe water faces a challenge that does not stem from industrial activity, but from the earth itself. That is why we propose this "problem-solving" solution with the aim of improving the lives of many communities.

The Arduino Control System

Hardware Components

1

Microcontroller: Arduino (Uno or Nano) managing the logic.

2

Relay Module: Acts as a bridge between the low-voltage Arduino and the high-voltage pumps and motors.

3

Actuators: Peristaltic or Submersible Pumps: For water transfer.

  • DC Motor / Stepper Motor: To drive the agitator paddle.
  • Solenoid Valve: To control gravity-fed flow.
4

Sensors: Ultrasonic Sensor (HC-SR04): To monitor tank levels and prevent overflows.

5

User Interface: LCD Display (16x2 with I2C): Displays real-time water status, tank levels, and system alerts.

  • I2C Module: To reduce the number of wires connected to the Arduino (only 4 pins).
  • Real-time monitoring: Shows if the water is "Filtering", "Full", or if there is an "Arsenic Alert".
