Golf course, sports field, event activities (preventing lightning accidents) strikealert.com.au

Construction / outdoor work safety

Construction, power, communication towers, oil and gas, mining, etc. open-air operations

Early warning of thunderstorms to arrange shutdown and evacuation times

Maritime / water activities

Sailing, yachting, water sports lightning warning

Weather and security assistance

Small weather stations, farms, pastures, scenic areas lightning monitoring

Record thunderstorm trends: approaching / away / stationary

Working principle (simplified)

Lightning discharge generates very strong low-frequency electromagnetic pulses that spread far.

The LD-3000 has an internal antenna to receive this signal. The signal strength is converted into distance and intensity.

The algorithm filters interference (motors, high-voltage electricity, mobile phone signals, etc.) to reduce false alarms.

Output: Distance, trend, sound, light, and vibration alarms.

Difference from radar

LD-3000: Measuring lightning electromagnetic signals → Warning of thunderstorms, lightning protection.

Radar (such as speed measurement / collision prevention): Emit radio waves → Measuring distance and speed of objects
