Introduction
Greenhouses are controlled environments where automation can improve efficiency. PIR sensors contribute by detecting pests, tracking workers, and automating responses.
Applications in Greenhouses
Pest Detection
Detect larger animal pests like rodents, rabbits, or birds that enter the greenhouse. Trigger alarms or deterrents.
Worker Tracking
Track worker movements to optimize workflow and ensure safety.
Automated Operations
Turn on lights, irrigation, or ventilation based on worker presence.
Security
Detect unauthorized entry after hours.
Sensor Requirements
- Humidity resistance: Greenhouses are humid; sensors must be protected.
- Temperature range: Wide range, possibly with heaters for cold climates.
- Animal differentiation: Distinguish between small pests and workers.
Case Study: Commercial Greenhouse
A large greenhouse installed PIR sensors to detect rodent activity. When rodents were detected, ultrasonic deterrents activated. Rodent damage decreased by 80%.
Conclusion
PIR sensors add intelligence to greenhouse operations, improving pest control and worker efficiency.
