It has become an essential structural design in every city as it helps to reduce road accidents and increase security. Many designs and construction have been made by researchers and engineers and all has been geared toward the design of a streetlight that is energy conservative, less expensive and automatically operated to eliminate the error associated with manual operation by humans. Most streetlights installed in are powered by batteries charged by a solar panel. Due to inadequate charging of the batteries, they end up being drained and are unable to be charged to power the streetlight. This design provides a system that helps maintain the batteries by keeping them from over-drained condition. A 12V dc battery which is mostly used is fully charged to 12.6V dc and when used, reduces to a useful voltage of 12.1V to 10.5V. Batteries are best maintained if the battery is no allowed to reduce in voltage below 12.3V before recharging it. This design is achieved using Arduino microcontroller which when programed will be able to read the voltage from the battery and use the information to cut off the power supply going to the streetlight by de-energizing a dc relay.

The Federal Government of Nigeria made a giant step in the communication sector by launching five satellites into orbit, NigeriaSat-1, NigComSat- 1, NigeriaSat-2r, NigeriaSat-X and NigComSat-1R. Though faced with challenges,Nigeria and her citizens are utilizing the benefits of satellite communication in several ways such as Speedy internet facility, distance learning, improved security, GPS services, GSM communication, TV and Radio Broadcasting. For Nigeria to make any headway in its quest to bridge the technology gap through communication satellite, increase in penetration of broadband services and adequate funding is needed urgently.
