Product Decription
- The 3mm LDR (Light Dependent Resistor) sensor changes its resistance based on the amount of ambient light that strikes its surface. LDRs, also known as photocells, are commonly used in light-sensing applications such as automatic outdoor light switches or indoor light control systems.
- This LDR sensor performs well in both light and dark environments. Light-dependent resistors, or photoresistors, are a fundamental component in electronics, especially when you need to detect ambient light levels. As the light hitting the sensor increases, the resistance between its two leads decreases.
- The sensor is made of two cadmium sulfide (CdS) photo-conductive cells, which have a spectral response similar to that of the human eye. The resistance of these cells decreases as light intensity increases. Common applications for this product include smoke detection, automatic lighting control, batch counting, and burglar alarm systems.
