蚊音雷达BuzzGuard

🎯 Hear the mosquito, then eliminate it!

That "buzz" in your ear late at night—it comes and goes, but you can't find it even with the lights on? Mosquito radar turns your phone's microphone into a mosquito-detecting radar: it analyzes ambient sound in real time, locks onto mosquito wingbeat frequencies between 200-700Hz, confirms the target, and tells you the approximate direction—the rest is up to your electric mosquito swatter.

📡 Core Functions

【Mosquito Sound Detection Radar】
· Real-time FFT spectrum analysis, focusing on the 200-700Hz mosquito wingbeat frequency band

· Multiple discrimination based on frequency stability, signal-to-noise ratio, and peak prominence, filtering out human voices and music

· Automatic identification and suppression of ambient constant sounds (fans, electrical noise), preventing false alarms

· Three adjustable sensitivity levels, suitable for bedrooms, nurseries, and outdoors

【Directional Scanning & Semi-Localization】
· After detecting a signal, hold the device for 8 seconds and rotate it at a constant speed.

· Polar coordinate heatmap displays the direction of the strongest signal, providing a reference location.

· Honest explanation: Single microphone has limited directionality; results are for reference only—but better than nothing.

【White Noise for Sleep】
· White noise / pink noise / brown noise + insect chirping, breeze, flowing water, campfire, ocean waves, forest sounds

· Seamless loop playback, automatic stop after 15/30/60 minutes timer

· Independent volume adjustment, continuous background playback

【Mosquito Repellent Knowledge Base】
· Why do mosquitoes specifically target you? The truth about blood type, body temperature, and carbon dioxide

· Infant and toddler mosquito prevention guide, proper treatment after bites

· Mosquito repellent plants, product selection and reviews – all practical information

【Detection Statistics】
· Today's events, consecutive days of protection, 24-hour active distribution

· All real records, allowing you to understand the mosquitoes' routines in your home

🔒 Privacy Commitment

· Audio is analyzed locally in real time; it is not uploaded, stored, or discarded immediately after analysis.

· No registration or internet connection required; core functions are completely offline.

· No personal data collected, no ads, no tracking

⚠️ Instructions for Use

The Mosquito Radar is an auxiliary detection tool. Mosquito flight sounds are weak, and detection effectiveness is affected by environmental noise, distance, and the phone's microphone. Please treat it as your "ear amplifier," not an absolute guarantee.

Tonight, let the radar keep watch for you. 🌙

🎯 Hear it. Find it. End it.

That midnight whine circles your ear, then vanishes the second you turn on the light. BuzzGuard turns your phone's microphone into a mosquito detection radar: real-time audio analysis locks onto the 200-700Hz wingbeat band, confirms the target, and points you in its rough direction. The rest is between you and your swatter.

📡 KEY FEATURES

【ACOUSTIC RADAR】
· Real-time FFT spectrum analysis focused on the 200-700Hz mosquito wingbeat band
· Multi-criteria detection: frequency stability, SNR and spectral peakiness filter out voices and music
· Automatic suppression of constant environmental tones (fans, electrical hum)
· Three sensitivity levels for bedrooms, nurseries and outdoors

【DIRECTION SCAN】
· When a signal is confirmed, rotate slowly with your phone for 8 seconds
· A polar heat map reveals the strongest signal sector
· Honest note: a single phone mic has limited directionality — results are indicative, not exact

【SLEEP SOUNDS】
· White, pink and brown noise plus crickets, breeze, stream, campfire, ocean and forest
· Seamless looping with 15/30/60-minute sleep timers
·Independent volume control and background playback

【MOSQUITO KNOWLEDGE】
· Why mosquitoes pick you: blood type, body heat and CO2
· Safe protection for babies, proper bite aftercare
· Repellent plants and product reviews

【DETECTION STATS】
· Daily events, streak days and 24-hour activity distribution
· All real records — learn your mosquitoes' schedule

🔒 PRIVACY

· Audio is analyzed locally in real time — never uploaded, never stored
· No account, no internet required for core features
· No personal data collected, no ads, no tracking

⚠️ NOTE

BuzzGuard is an assistive detection tool. Mosquito wingbeats are faint; results vary with ambient noise, distance and microphone quality. Treat it as a hearing enhancer, not a guarantee.

Tonight, let the radar stand watch. 🌙
