In electronics, a light sensing component is the Light Dependent Resistor (LDR). The street light’s control mechanism senses brightness using a light sensor and decides whether to switch on the light. These days, street lights are far more intelligent and can turn on as soon as ambiance decreases.

In cities where the daylight didn’t vary much, there weren’t any significant issues, except when clouds blocked sunlight. They always turned on at a specific time in the evening and turned off early in the dawn. The Evolution of Automatic Street Lightsīack when I was a kid, street lights were not as intelligent as they are now. Let’s start with the basic science that makes street lights intelligent. But without a solid design, the street lights we take for granted may not turn on when they’re supposed to. Of course, street lights might sound dull compared to the exciting electronics behind technologies like the Internet of Things (IoT). I missed out on an experience of a lifetime, hidden in pitch darkness. But a few nights ago, I desperately missed the familiar glow of street lights while attempting to observe sea turtles laying their eggs at a local beach.

In fact, I can’t fall asleep at all if any lights are left on.
