Problem Statements:

Growing plants in limited space by amateurs

Description:
Many people would like to grow plants (basic vegetables and herbs for the kitchen for example) but do not have enough space in their house to do so. They also may not have the expertise to grow plants, so would need an easy DIY solution. Solving this is important, especially in urban areas, because it will help households become more self sufficient.

Why we chose this problem?

We were inspired by Kimbal Musk, Elon Musk's brother, and his project to farm in urban spaces. Urban spaces general lack the resources required to farm conventionally. Therefore he had to get creative and find a solution to farm in indoor spaces - with limited space, light and soil nutrients. If the device is used to grow plants indoors, we could see a shift in the way people consume their food. It would reduce wastage of food and could improve the air quality of the users apartment. We attempted to make a cheaper version of the same product so that it could be feasibly used in India.

Step 2: Why We Chose Lazy Planter?

Why we chose Lazy Planter?

Out of the above ideas, the herb rack would be the easiest to make while the farm inside a building would be the most difficult. I personally would like to build the plant and forget box. Making the idea would be a challenge, but it is not completely outside my skills. With some hard work this project could easily be built within 2 months. Since the project is small scale, the resources required for it should be manageable. The most expensive part of the project would be the arduino. Other materials could easily be sourced from hardware and electrical stores.

I have rated the idea as exciting because I believe automation improves a person's life. For example, if a farmer could automate the process of growing his crops, he would only be required to passively keeps track of the progress of his plants. This would save him time and money (in labour cost). Therefore, an automated growing process is an existing solution to the problem of growing plants in small spaces. It would work both as an end user product for apartments as well as a concept/prototype for larger industrial scale solutions.

Now, next is a step by step guide on how we made the project.

Step 3: Circuit Diagram

Follow this diagram and make the connections accordingly.

Step 4: Step 2: Connect the Moisture Sensor to Controller and the Breadboard.

Attach the moisture sensor to the controller and then attach the controller to the Arduino. Refer to the circuit diagram for detailed connections.

Step 5: Step 3: Connect the Pump to Relay.

Follow the circuit diagram to connect the relay. Attach the battery to the relay.

Step 6: Step 4: Connect the Arduino and Relay to the Breadboard.

Connect the Relay to the breadboard. Attach the Arduino to the breadboard according to the circuit diagram.

Step 7: Input the Following Code on the Ardunio IDE

const int sensor_pin = A0; /* Soil moisture sensor O/P pin */

  float moisture_percentage;
  int motorPin = 13;
  const int min_moisture = 50;
  
void setup(){
  pinMode(motorPin, OUTPUT); 
  Serial.begin(9600); /* Define baud rate for serial communication */
}
void loop() {
  
  int sensor_analog;
  sensor_analog = analogRead(sensor_pin);
  moisture_percentage = ( 100 - ( (sensor_analog/1023.00) * 100 ) );
  Serial.print("Moisture Percentage = ");
  Serial.print(moisture_percentage);
  Serial.print("%\n\n");
  
  if(moisture_percentage > min_moisture) {
        PumpWater();       
    } 
  else{
    StopPump();
  }
  delay(1000);    
}
void PumpWater(){
   digitalWrite(motorPin, HIGH);
  delay(1000);
 
}
void StopPump(){
  digitalWrite(motorPin, LOW);
  delay(1000);
}

Step 8: Upload the Code to the Arduino. Assemble the Device

Upload the code to Arduino

Attach the pipe to the pump

Put the moisture sensor into the planter

Put the pump into the water tank

Add water to the tank

Put the deve inside a case.

Attach the Wall adapter to the arduino

Plug and enjoy
