How do the streetlights turn on automatically at night

When no light hits it, it has high resistance -- it conducts electricity poorly. In an extremely simple circuit, you would wire a CdS cell directly to a relay (see How Relays Work), so that a lot of light would energize the electromagnet and a small amount of light would not. Usually, however, a CdS cell cannot draw enough current to activate

Light Sensors: Units, Uses, and How They Work

Light sensors seem pretty simple. They sense the light, just like a thermometer senses the temperature, and a speedometer senses speed.Temperature and speed are easy to comprehend because we sense them in a straight-forward way. But light is very complicated.
