Description
20mm LDR Sensor Photoresistor Photo Cell 20528 GL20528 – ldr light dependent resistor
The resistance of the 20mm GL20528 Light Sensitive Photoresistor LDR changes with ambient brightness and helps automate lighting functions. As intensity increases, resistance drops, making this ldr light dependent resistor ideal for smart switches and sensing projects. Additionally, makers evaluating the cost of ldr sensor appreciate that it integrates cleanly with a reliable light dependant resistor circuit. If you need to measure ambient light with minimal complexity, this solution works effectively in both bright and dark environments.Two Cadmium Sulphide photo-conductive cells provide eye-like spectral response, and resistance falls steadily with increased illumination. Common applications include batch counting, automatic lighting, smoke detection, and burglar alarms.
