How It Works
Discover the science behind our solar-powered ultrasonic deer repellent. Advanced technology creates an effective, humane barrier that deer naturally avoid.
The Complete Process
From detection to deterrence in under half a second
Motion Detection
PIR sensor detects deer movement
Key Features:
- Passive infrared (PIR) technology detects body heat differences
- 110° detection angle covers wide area
- 30-foot detection range optimized for deer size
- Response time under 0.5 seconds for immediate activation
The PIR sensor uses pyroelectric material that generates electrical signals when infrared radiation (body heat) changes within its field of view.
Ultrasonic Emission
25kHz frequency disrupts deer behavior
Key Features:
- Frequency specifically calibrated for deer hearing sensitivity
- Sound pressure level: 90-100 decibels at source
- Inaudible to humans (hearing range typically 20Hz-20kHz)
- Variable frequency prevents habituation
Deer hearing range extends to 30kHz, making 25kHz frequency uncomfortable but not harmful, similar to how high-pitched sounds affect humans.
LED Flash Deterrent
Bright light adds visual intimidation
Key Features:
- High-intensity white LED creates startling effect
- Particularly effective during dawn/dusk feeding times
- Flash duration 2-3 seconds to maximize impact
- Combined with ultrasonic for multi-sensory deterrent
Sudden bright light triggers deer's flight response, as it simulates potential predator presence or human activity.
Solar Power System
Continuous operation without maintenance
Key Features:
- 6V/2W polycrystalline solar panel
- 2000mAh lithium-ion battery backup
- Intelligent power management optimizes battery life
- Works even during extended cloudy periods
Advanced MPPT (Maximum Power Point Tracking) ensures optimal energy harvest from solar panel under varying light conditions.
The Science Behind the Technology
Research-backed principles ensure maximum effectiveness
Why 25kHz Frequency?
Research shows deer hearing is most sensitive between 1-30kHz, with peak sensitivity around 8-16kHz. Our 25kHz frequency is high enough to be uncomfortable for deer while remaining completely inaudible to humans. This frequency creates an 'acoustic barrier' that deer naturally avoid.
Key Insight
Optimal frequency selection based on deer auditory research
Motion Detection Science
PIR sensors detect changes in infrared radiation (heat signatures). When a deer enters the detection zone, its body heat contrasts with the background temperature, triggering the sensor. The 110° angle and 30-foot range are optimized for deer body size and typical approach patterns.
Key Insight
PIR technology provides reliable, weather-resistant detection
Solar Efficiency
The 6V/2W solar panel generates enough power to operate the device continuously. Even with just 4 hours of sunlight, the system can run for 7+ days. The 2000mAh battery provides backup power for extended cloudy periods or winter conditions.
