Express post delivery (2-5 business days)

A pack of 50 through-hole photoresistors (light-dependent resistors / LDRs) with a 5 mm diameter sensing element. These components change their resistance based on the amount of light hitting the sensor — resistance decreases as light intensity increases — making them a simple and inexpensive way to detect ambient light levels.

Photoresistors are commonly used in automatic lighting systems, light-following robots, and basic light-level sensing circuits. They pair well with a voltage divider and an analogue input on any microcontroller such as Arduino or Raspberry Pi.

Key Features

  • 50-Piece Pack – Bulk quantity for classrooms, prototyping, or multiple projects
  • 5 mm Diameter – Standard through-hole form factor, breadboard-friendly
  • Analogue Light Sensing – Resistance varies with ambient light intensity
  • Simple to Use – No special library or protocol required; works with a basic voltage divider

Specifications

  • Type – 5800B Photoresistor (LDR)
  • Diameter – 5 mm
