Dover, 1987. motion detector or electric eye — Puzzles Crossword Clue. An example photocell is the Advanced Photonix PDV-P5002, shown in Figure 21.2.In the dark, this photocell has a resistance of approximately 500 kΩ, and in bright light the resistance drops to approximately 10 kΩ.The PDV-P5002 is sensitive to light in the wavelengths 400-700 nm, approximately the same wavelengths the human eye is responsive to.
