Description
These 3mm F3 Photodiode sensors are high-speed, high-sensitivity components designed to detect light with precision and speed.
They serve as a fast and reliable alternative to traditional photoresistors (LDRs), making them ideal for light-sensing applications in electronics and embedded systems.
Encased in a standard 3mm plastic package, these photodiodes are compact, responsive, and perfect for use with Arduino, Raspberry Pi, and other microcontrollers in both digital and analog light detection projects.
