When light increases, resistance across the two leads decreases, making it suitable for responsive smart lighting. In everyday builds, a light dependant resistor ldr enables effortless ambient-light sensing; furthermore, checking total light dependent resistor price helps plan classroom batches and DIY kits. Two Cadmium Sulphide (CdS) photo-conductive cells exhibit a human-eye-like spectral response, and therefore, this light dependant resistor ldr fits smoke detection, automatic lighting control, batch counting, and burglar alarms, while supporting ldr light circuit integration with ease.

Description
7mm LDR Resistor Sensor Photo Cell 20528 GL20528 – light dependant resistor ldr
This compact device works as a light dependant resistor ldr and actively changes resistance with ambient light on the sensing surface. Moreover, in many DIY builds, users often compare the light dependent resistor price before selecting sizes, especially when planning an ldr light circuit for automation. Because this light dependant resistor ldr is simple and reliable, it suits outdoor ON/OFF lamps and indoor night-light switches, while still remaining easy to test on breadboards.When light increases, resistance across the two leads decreases, making it suitable for responsive smart lighting.
