In this video I hope to explain how to activate a magnetic contactor using a photo cell switch.
What is Photocell?
A photocell can be defined as; it is a light-sensitive module. This can be used by connecting to an electrical or electronic circuit in an extensive range of applications like sunset to sunrise lighting that mechanically turns on whenever the intensity of light is low. These are also used in other applications like intruder alarms and also automatic doors.
Applications of Photocells
Photocells are used in automatic lights to activate whenever it gets dark, and the activation/deactivation of streetlights mainly depends on the day whether it is day or night.
These are used as timers in a running race to calculate the runner’s speed.
Photocells are used to count the vehicles on the road.
These are used instead of photovoltaic cells & variable resistors.
These are used in lux meters to decide the light intensity.
These are used as switches as well as sensors.
These are used in burglar alarms to protect from a thief.
