Problem:

Pests (e.g., rodents, birds, insects) destroy crops, leading to significant yield losses. Traditional methods like pesticides harm ecosystems, while manual scare tactics are labor-intensive and ineffective.

Benefits to Farmers:

– Non-Toxic Pest Control: Uses motion detection and deterrents (sound/light/vibration) instead of chemicals.

– Cost-Effective: Replaces expensive pest control services.

– 24/7 Protection: Operates autonomously, even at night.

– Reduced Crop Loss: Early detection of pests prevents widespread damage.

Solution:

Deploy PIR sensors (HC-SR501) to detect motion near crops. When triggered, activate vibration motors, speakers, or IR lasers to scare pests. Use ESP32 to coordinate sensors and deterrents.

Process:

1. Motion Detection:

– PIR sensors detect heat signatures of animals entering crop zones.

2. Deterrent Activation:

– ESP32 triggers vibration motors (to simulate movement), speakers (play predator sounds), or IR lasers (create flashing light barriers).

3. Optional Enhancements:

– Integrate ultrasonic sensors to detect pests in dark environments.

– Use GPS modules to log pest activity locations for targeted prevention.

Parts Used:

– ESP32, PIR Sensors (x5), Vibration Motors (x10), Speakers (x6), IR Lasers (x10), Ultrasonic Sensors (x9), GPS Modules (x2), Breadboards (x6).
