Solar Water Distiller 3D Model

It is a 3D Model of Solar Water Distiller created in Blender

Schematics

Solar Water Distiller Flowchart

Butterfly Valve

The following video shows how the Butterfly valve opens to let the water into the upper pipe and once the water reaches a particuar level, using a water sensor, MSP-430 guides the servo motor to close the butterfly valve.

Condensation

This video shows the water condensed on the transparent sheets after 10-15 minutes of continuous heating of water.

Water Pump

This video shows the extraction of water from the upper pipe once a particular water level is reached using a water pump.

Code

Solar Water Distiller Code

C/C++
Its the code for controlling the MSP-430 microcontroller.
#include <Servo.h> 
long previousMillis = 0;
 
Servo myservo;  // create servo object to control a servo 
                // a maximum of eight servo objects can be created 
 
int pos = 0;    // variable to store the servo position 
int pumpState =0;;
void setup() 
{ 
  myservo.attach(P2_3);
  pinMode(P2_4,OUTPUT);
  pinMode(P1_3,INPUT);
  pinMode(P1_4,INPUT);
  //pinMode(P
  Serial.begin(9600);// attaches the servo on pin 9 to the servo object 
} 
 
 
void loop() 
{ 
  //myservo.write(90);
  if(!digitalRead(P1_3))
  {
   myservo.write(20); 
   Serial.println("Servo on");
   delay(20000);
  }
  else
  {
    myservo.write(90);
    Serial.println(digitalRead(P1_3));
    Serial.println("Servo off");
  }
  unsigned long currentMillis = millis();
  if(currentMillis - previousMillis > 30000)
  {
    previousMillis = currentMillis;
    digitalWrite(P2_4,HIGH);
    Serial.println("pump on");
    delay(10000);
    digitalWrite(P2_4,LOW);
    Serial.println("Pump off");
    //Serial.println(analogRead(P1_3));
  }
