Reasonably choose the height of the solar street light, so that you spend less money!
Many customers don’t know how to choose the height of street lights. Often due to their improper choice, the road lighting conditions are not good or the extra money is spent!
We once encountered a very interesting incident. The other party asked for a solar street lamp and asked for a pole length of 8 meters. However, when I asked how wide the road he installed was, his answer surprised me, because his answer was 3.5 meters. It can be seen that there are still many buyers who don't know much about the relationship between road width and light poles. Today, we will talk about how to choose the right height of the solar street light pole according to the width of the road.
As usual, the places where solar street lights are installed can be roughly divided into residential roads, street roads and urban branch roads. The road width of the community is usually 4-6 meters, and the height of the solar street light pole should be 4-6 meters. The width of the road in the village is usually 4~5 meters, and the height of the solar street light pole should be 4~5 meters. The width of the urban branch road is usually 6~8 meters, and the height of the solar street light pole should be 6~8 meters.
Of course, the choice of the height of the solar street light pole is also related to the density and type of passing vehicles. But the most important thing is that the road is wide as usual. I hope that readers can choose the height of the light pole according to the road width after reading this article.

Q: Which external components will affect the radar module and what should be paid attention to?
A: 1) The influence of the buzzer switch on the radar module: → The buzzer switch will disturb the power supply. The buzzer and switch should be placed far away from the radar when designing the structure; →The buzzer switch and 10.525G signal will be mixed. The product software will shield the interference during design, and ignore the radar induction signal when the buzzer switch and indicator light flash; →The indicator light and 10.525G signal will be mixed, the sensor software algorithm should be updated, and the specific software version should be used for the scene with strong interference. 2) The influence of the relay on the radar module: →The on and off of the relay will cause a big disturbance on the power supply. When designing the structure, place the radar sensor far away from the relay, or make a shield on the structure; →The movement of the metal shrapnel of the relay is Doppler interference. When designing, the terminal software will shield the relay interference, ignoring
Q: How to reduce the sensing distance on the back of the radar module?
A: 1) Under normal circumstances, after the antenna form is fixed, the pattern is basically determined, and the antenna back lobe optimization can consider the use of a more directional antenna; 2) When designing the antenna: Keep the antenna surface away from the edge of the board as much as possible, increase the size of the board as much as possible, and spread the ground on the bottom as much as possible. Consider placing a shielding cover on the back of the module to reduce the radiation effect of the antenna on the back of the module; 3) The test environment will affect the corresponding test results: the general indoor space has reflections, which will cause the sensing distance behind the module to be relatively far. But in an outdoor environment, this situation will be reduced.

Q: What should I pay attention to when building the provided reference version design data? Which parameters have a greater impact on the consistency of the module?
A: 1) The thickness of the board (or the laminated structure of the board) and the dielectric constant of the board. 2) The consistency of sheet thickness and dielectric constant is most closely related to the consistency of the module.
Q: How do you ship the goods and how long does it take to arrive?
A: We usually ship samples and small quantities of products that customers need urgently with DHL, UPS, FedEx or TNT. It usually takes 3-5 days to arrive. High-volume product transportation is available for airline or maritime transportation. The shipping time is updated according to the actual situation of the shipping company.
Q: For end products that need to be connected to the Internet, what should be paid attention to nowadays when radar sensors and wifi/BT/NB coexist?
A: 1) Stagger as much as possible in space, and extend the distance between the antenna of the IoT module and the antenna of the radar; 2) Stagger the time as much as possible, and shield the radar sensor signal when the IoT module communicates; 3) Stagger the frequency as much as possible, and avoid the corresponding communication frequency by adjusting the frequency of the radar sensor.
