LDR photoresistors in assortment

Photoresistors, also known as light dependent resistors (LDRs), are widely used in electrical circuits to control functions based on light levels. Here are some basic applications of photoresistors: Automatic Lighting Control: Photoresistors can be used to automatically turn on and off street lights, garden lights and house lights when the level of natural light falls below a certain threshold. Emergency lighting: In security systems, photoresistors are used to activate emergency lighting in the event of a sudden power outage or low light levels. Alarm devices: Using photoresistors as sensors, it is possible to create various alarm devices that are activated when there is a change in illumination, for example, when a beam of light is interrupted by an intruder. In measuring instruments: Photoresistors can be used to create devices that measure light levels under different conditions, such as in photography to determine exposure. These devices are easy to use, inexpensive, and can be integrated into a variety of electronic projects, making them a popular choice for a variety of applications.
