How does a street light work?

Updated: Aug 7, 2020

- Street light contains photocells that detect light.

- Photocells are light sensitive sensors that respond to amount of light detected.

- If light is needed(night time),the sensor stimulates the computing unit inside the street light to activate the flow of electricity.

- If there is too much light(day time),the sensor will deactivate the streetlight.
