The characteristics of solar Radar Speed Limit Sign display (2 digits):
1. When the vehicle enters the speed feedback display solar radar speed display (2 digits) area (about
600m in the front of the logo), the microwave radar will automatically detect the speed of the vehicle
and display it on the radar speed display
(2) The number of digits on the LED display shows the current
speed in time to remind the driver to pay attention to reduce the driving speed, thus effectively reducing
the occurrence of road traffic accidents caused by over speed.
2. The solar radar speed display (2-digit) outer box adopts an integrated chassis, which has beautiful design
and strong waterproof effect.
3. Solar Radar Speed Limit Sign display (2 digits) uses super bright beads, color matching, and clear colors.
4. Solar Radar Speed Limit Sign display (2 digits) is installed by hoop, which is easy to install and convenient.
5. The solar radar speed display (2 digits) is powered by solar panels, which is energy-saving and environmentally
friendly.
6. Solar radar speed display (2 digits) can be connected to the battery or lithium battery.
7. The solar radar speed display (2 digits) uses the exclusive audio debugging software of our company
.
Third, the principle of solar radar speed display (2 digits):
The solar radar speed display (2 digits) mainly uses the Doppler Effect principle: when the target is close to the radar
antenna, the reflected signal frequency will be higher than the transmitter frequency; otherwise, when the target is
away from the antenna The reflected signal frequency will be lower than the transmitter frequency. In this way, the
relative speed of the target and the radar can be calculated by changing the value of the frequency. It has been widely
used in industries such as police speeding test
