Red light sensor
Web21. mar 2024 · Here is a simple circuit that uses a transparent red LED as the light sensor that switches on a white LED when the red LED is in dark. Ordinary transparent LEDs function as light emitters and light detectors. These detect a narrow band of wavelengths of light and their p-n junction forward biases to generate around 1V voltage with a minute ... Web14. sep 2004 · If it is, then the motion detector uses a photocell light sensor to detect whether it is dark outside or not. If it is dark then upon detecting motion it turns on the light. If it isn't dark then upon detecting motion it only flashes the red LED. If it is dark, then the motion sensor should turn on the lights when it detects motion.
