Photocell Sensors: Enhanced Safety and Convenience

Have you ever seen a light turn on when the sun started to set? You might have witnessed this occurring with a streetlight because many streetlights are controlled in this manner. Perhaps you have seen a light like this switch on at a seemingly random interval at some point during the day. Maybe you even happened to notice that this happened during a particularly dark period of an otherwise bright day.

If you were wondering how this worked and are very unfamiliar with circuitry and lighting technology, then you should know that the basic principle here is that these lights are not manually controlled. In many cases, they are controlled by means of a device known as a photocell sensor.

These sensors are relatively simple devices and without getting too into the weeds of their operation, this is how they work. They are connected to the circuit that controls power to a light, and they are also sensitive to the ambient light. When a photocell sensor detects atmospheric light, such as from the sun, it shuts off power to the light that it controls. That’s why streetlights are not powered on in the daytime.

When the same sensor does not detect adequate ambient light, it powers the device it controls on. That’s why lights such as street lights automatically go on when it gets dark out. There are other lights that are powered by these sensors that go on when it gets dark, and in fact, many light fixtures can be controlled by a sensor switch such as this.

Among the light bulbs that are commonly controlled by sensors like these are street lights, parking lot lights, some security lights, and others. These types of sensors are a very cost-effective way to ensure that lighting lights up when it needs to and goes dark to save power when it isn’t. They’re also safer and more effective than timers, and they last a very long time.

Consider the following. For security or parking lot lighting to be effective, it must remain lit not only from dusk to dawn but also any other time that it was too dark out to see well. That is to say, there are other times during the day that a light might need to be switched on, generally, whenever the ambient lighting was inadequate to ensure safety.

Outdoor lighting like this can be controlled by timers, but if the timers fail, then the lights won’t switch on when they need to. Additionally, timers only switch on lights with respect to time and not with respect to the brightness of the surroundings. If a powerful storm were to darken a region and the lights there were controlled only by timers, then the lights would not go on and it would constitute an issue of safety.

In addition, sensors like these can save you money and enhance safety as the natural light shifts throughout the year. Timers would become inefficient as the light changed throughout the year. For example, it would come necessary to adjust the timers as the seasons change, but a photocell sensor never needs to be adjusted. It works effectively the same way, as it is supposed to, every time.

Whether you’re looking for one of these sensors for a light on your outdoor wall or you really need to outfit an entire system with sensors to enhance efficiency and safety, your best bet is to visit where you will find plenty of viable options.
