Daylight sensors are devices that detect the amount of natural light in an environment. They are commonly used in lighting systems to automatically adjust the brightness of artificial lights based on the available daylight. This helps save energy and maintain optimal lighting conditions. These sensors can be found in various applications, including smart homes, street lighting, and commercial buildings. By using daylight sensors, users can reduce electricity costs and enhance comfort by ensuring that spaces are well-lit when needed, while minimizing unnecessary energy consumption during daylight hours.
