Farmers face heavy losses when:
- Wild animals (boars, monkeys, elephants, etc.) enter farms and destroy crops.
- Unknown humans enter fields to steal produce or damage property.
Traditional scarecrows or fencing are ineffective, and electric fencing is expensive and dangerous.
This model solves a common issue faced by farmers – crop damage from wild animals or theft. When any object passes through the field boundary, this sensor detects the movement and triggers an alarm.
It can be solar-powered and works day and night. With a real version, farmers will get alerted early and protect their crops efficiently and safely.
A low-cost Intrusion Detection System using:
- Infrared (IR) sensors or Laser or 2 layer of gi metal wire
- Buzzer or Alarm system
- LED lights or Mobile Notification (optional)
- Powered by solar panel or battery
It detects movement at night or day, and alerts the farmer instantly through sound or light.
Working Model Setup:
- Create a mini farm model using cardboard.
- Install IR sensors (or laser setup) along the farm boundary.
- Connect sensor → control system → buzzer & LED.
- When something crosses the sensor beam:
- Buzzer sounds
- Light turns on
- (Optional) Mobile alert via GSM/Bluetooth if using Arduino.
How It Works (Demo):
- Keep a small toy animal/human and pass it through the sensor area.
- The sensor beam is interrupted.
- Immediately, buzzer sounds, lights blink – alerting the “farmer”.
Science Concepts Used:
- IR and laser sensor technology
- Light interruption detection
- Electrical circuits and alarms
- Application of renewable energy (solar panel)
- Real-time problem-solving with automation
This project is low-cost, scalable, safe, and solves a real problem faced by rural farmers – a perfect fit for Inspire Award or science exhibitions.
