Description
05 Pc LDR light dependent resistor is a type of photocell that finds excellent use in light sensing device application, whether it is automatic outdoor light ON/OFF switch or an Indoor automatic light switch.
This LDR 3mm changes resistance with the change in the ambient light exposure on the surface of the sensor. Photoelectric control, automatic camera measurement, indoor light control, alarm, industrial control, light control switch, light control lights, electronic toys, etc.
The LDR 3mm sensor works best in both Light and dark regions. Light-dependent resistors or photoresistors are a staple of electronics. If you need a way to sense the level of ambient light then there is no easier way to do it. As the light on the sensor increases then the resistance across the two leads decreases.
