How a solar powered flood alert warning system works?

Hence, this project aims to design the solar powered flood alert warning system by using solar energy as the power supply. This system will send message using GSM to the residents to notify them about the flood occurred. In this project, three LEDs were used to indicate the height of the water levels which are safe, alert and danger conditions.

How do Solar traffic lights work?

Solar traffic lights are signalling devices powered by solar panels positioned at road intersections, pedestrian crossings and other locations to control the flows of traffic. They assign the right of way to road users by the use of lights in standard colors (red - amber/yellow - green), using a universal color code .

Why should you install solar security lights in your home?

Illuminating these spaces allows people to continue to enjoy them with added safety and security. Solar security lighting would increase the visibility and usability of these spaces and provide a green way to provide power for the lights. The solar would be easily installed without displacing the area or causing considerable downtime.

When should you use a solar traffic light?

Portable, solar-powered, traffic light used when construction workers must narrow a 2-way street to a single lane and must emplace traffic controls for safety. Solar traffic lights can also be used during periods following natural disasters, when the existing street lights may not function due to power outages and the traffic is uncontrollable.

Why do Solar traffic lights use LED lights?

Most solar traffic lights use LED lamps as they are more reliable and have more advantages over other lighting devices like CFL lamps as they are more energy efficient, have a longer life span and turn on and turn off quickly. Solar traffic lights contain enclosures which house the batteries and the control panel circuitry.

Why do solar lights need to be turned off?

Dimming the lights, or having them shut off completely, reduces the impact on the grid or lowers the required solar power system. In addition, motion sensors can be used to increase the lights, or turn them back on, if someone enters the area after everything is closed.
