DAY NIGHT SENSOR (230V)

A day-night sensor is a device that is used to detect the presence or absence of light in an environment. It can be used to automatically turn on or off lights, or to trigger other events based on the level of light in a particular area.

There are various types of day-night sensors available, including photoresistor sensors, which detect changes in light levels using a variable resistor, and photovoltaic cells, which generate electricity when exposed to light. Some day-night sensors also use infrared technology to detect the presence of heat, which can be used to distinguish between day and night.

Day-night sensors can be used in a variety of applications, including energy-efficient lighting systems, security systems, and automated irrigation systems. They are often used in outdoor environments, such as in streetlights or in solar-powered devices, but they can also be used indoors to control lighting and other systems.
