Installing a Photocell Sensor
Read our blog for tips on the best lighting solutions for your business or facility, including our photocell sensors for outdoor lighting. Contact us today! What is a Photocell Sensor? Automatic lighting, such as streetlights, often uses photocell sensors—also known as photoeyes—to sense how much ambient light there is. ...
A Guide to Fire Alarm Basics – Initiation
A rate-of-rise detector utilizes an air chamber and a diaphragm. When a fire causes the air in the chamber to expand faster than it can escape out the vent, the increased pressure forces the diaphragm to close the contacts and initiate an alarm signal. This rate-of

How Do LED Street Light with Photocell Work?
A photocell is a device that reacts to changes in light intensity by changing its resistance. It has a wider range of sensitivity than a photodiode, but it is less sensitive overall. You need to apply a constant voltage to a photocell and then measure the changes in its resistance to determine the ambient light brightness.
