If a sensor system in a smart home collects personal data to
make decisions, is it ethical to use this data for targeted

SMART IRRIGATION SYSTEM

A Smart Irrigation System automatically waters plants based on soil moisture. Using a soil
moisture sensor, it detects the water content in the soil. If the soil is dry, the system turns ON
a water pump to irrigate the plants. If the soil is wet, the pump turns OFF. This ensures efficient
watering and prevents overwatering or underwatering.

Components Used

The different components used in the project are:
Arduino Uno: Processes input from the soil moisture sensor and controls the water pump.

Soil Moisture Sensor: Detects moisture levels in the soil and sends data to the Arduino.
Water Pump: Pumps water automatically to irrigate plants when soil is dry.

LEDs (Optional): Red LED indicates dry soil, Green LED indicates wet soil.
Resistors: Used with LEDs to limit current and with the water pump circuit to protect
components and control voltage.

Breadboard and Jumper Wires: Used to connect all components together and to the Arduino.

To build the Smart Irrigation System, follow the given steps:

STEP - 1 Connect the VCC (Power) pin of the Soil Moisture Sensor to the 5V pin of the
Arduino.

STEP - 2 Connect the GND (Ground) pin of the Soil Moisture Sensor to the GND pin of the
Arduino.

STEP - 3 Connect the SIG (Signal) pin of the Soil Moisture Sensor to the A0 pin of the Arduino.

STEP - 4 Connect the Anode of the Red LED to Digital pin 7 of the Arduino using a red jumper
wire.

STEP - 5 Connect the Cathode of the Red LED to GND on the Arduino (through a 330
resistor).

STEP - 6 Connect the Anode of the Green LED to Digital pin 6 of the Arduino using a green
jumper wire.

STEP - 7 Connect the Cathode of the Green LED to GND on the Arduino (through a 330
resistor).

STEP - 8 Connect the Positive Terminal of the Water Pump (DC Motor) to Digital pin 8 using
a blue jumper wire.
