If you need a way to sense the level of ambient light then there is no easier way to do it without an LDR/photo-resistor. The resistance of Light Sensitive Photoresistor LDR changes with the change in the ambient light exposure on the surface of the sensor. Light Dependent Resistor is a type of photocell that finds excellent use in light sensing device applications, whether it is automatic outdoor light ON/OFF switch or an indoor automatic light switch.

Two Cadmium Sulphide PhotoConductive Cells with spectral responses similar to that of the human eye. Cell resistance falls with increasing light intensity. The 20mm LDR or photoresistor sensor works best in both light and dark regions. The photo-resistors are a staple of electronics.

Applications of this product include smoke detection, automatic lighting control, batch counting, and burglar alarm systems. Furthermore, some of the applications are given below.

  •  Analog Applications:
    • Electronics scales – dual cell
