A photo sensor, also known as a photocell, photoresistor, or light-dependent resistor (LDR), is a type of light-sensitive device that changes its electrical resistance in response to changes in incident light intensity. These sensors are commonly used to detect and measure light levels and are employed in various applications to control lighting, trigger alarms, or perform other functions based on ambient light conditions
Photo sensors are essential components in various technologies and applications where light detection and control are necessary for energy savings, convenience, and automation.
