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.\n\nPhotoresistors 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.\n\nKey Features\n\n\n50-Piece Pack – Bulk quantity for classrooms, prototyping, or multiple projects\n\n5 mm Diameter – Standard through-hole form factor, breadboard-friendly\n\nAnalogue Light Sensing – Resistance varies with ambient light intensity\n\nSimple to Use – No special library or protocol required; works with a basic voltage divider\n\n\nSpecifications\n\n\nType – 5800B Photoresistor (LDR)\n\nDiameter – 5 mm\n\nPackage – Through-hole\n\nQuantity – 50 pieces\n\n\nIdeal For\n\nAutomatic night lights and street lighting controllers\nLight-following or light-avoiding robots\nAmbient light detection for displays and dashboards\nEducational electronics and Arduino/Raspberry Pi projects\n","vendor":"Little Bird","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3326,"title":"Default Title","sku":"LB-LS0633","price":0.62,"on_sale":false,"in_stock":true,"available_quantity":354,"option1":"Default Title"}]}
