1. LD2415H Speed Radar Is A Millimeter-Wave Radar Module Integrating Microstrip Antenna, Radio Frequency Circuit And Signal Processing Circuit. It Directly Outputs The Speed Information Of The Target And Can Be Used For Long-Distance Car Speed Measurement Of More Than 180 Meters. Using An Integrated Radio Frequency Chip, The Frequency Stability Is Extremely High And The Speed Measurement Accuracy Reaches 1km/H. 2. Widely Used In Speed Reminders And Early Warnings On Road Curves And Road Openings On Various Types Of Roads Such As Highways, Urban Trunk Lines, City And County Highways, And Urban And Rural Trunk Roads. 3. Install It On The Left Or Right Side Of The Road According To The Direction Of Road Vehicles, With A Height Of 1~2m; The Recommended Angle Between The Antenna Emission And The Road Is Less Than 10. 4. This Radar Only Detects Relatively Moving Targets In The Inspected Area, And Does Not Detect Completely Stationary Targets. The Output Result Is Information Such As The Speed Of The Nearest/Fastest Target In Relative Motion Within The Detection Area. 5. If There Are Obstructions Such As Water Or Metal In The Direction Of Radar Emission That Strongly Reflect Millimeter Wave Signals, The Radar Detection Effect Will Be Seriously Affected.
