6 FAQs about [Is the photocell a brand Is it safe ]

Are Photocell sensors a good burglar deterrent?

Many people use photocell sensors for energy savings, convenience, and safety. Specifically for outdoor lighting, photocell sensors are a good burglar deterrent because they can power your lighting on and off when you aren’t home. They are a convenience factor since you don’t have to worry about forgetting to turn lights off.

What are indoor Photocell sensors?

Indoor photocell sensors are similar to that of dimmer switches in that both increase and reduce the output of artificial light. Should I Use Photocell Sensors? Many people use photocell sensors for energy savings, convenience, and safety.

Can a photocell sensor control your home's lighting?

Controlling your home’s lighting automatically saves money and energy. Many people opt for timers to control their exterior and interior lighting. But there is another option: photocell sensors. What Is A Photocell Sensor? A photocell sensor is an electrical device that hooks up and communicates with a transformer.

How do Photocell sensors work?

Photocell sensors work like a timer switch in that they power light fixtures off and on automatically during a set “time”. They work a little bit differently though than timer switches because photocell sensors sense the natural light of the sun for controlling artificial light output from lighting fixtures. How Does A Photocell Sensor Work?

How do indoor Photocell sensors save energy?

Indoor photocell sensors increase and decrease the artificial light levels to save energy. For example, on a cloudy day when natural sunlight isn’t abundant, the artificial light from your fixtures will increase. When the sun is rising and natural light is making its way into your office, your artificial light source decreases.

Why do I need photocells?
