CdS Cells, also known as Cadmium Sulfide Cells, are a type of photo detectors used in optical sensing applications. These optical sensors measure light intensity and can be found in a variety of applications ranging from surveillance to tracking. One of the most common applications for CdS cells is the PDV-P8107. This particular application uses the CdS cell to monitor light levels and adjust the output of a device accordingly. In this article, we will take a closer look at this technology and explain its working principle.

The PDV-P8107 is an optical sensor designed to detect and adjust light levels within a given range. It uses a CdS cell, which contains an extremely sensitive layer of cadmium sulfide. When the light level is within the specified range, the CdS cell absorbs photons from the incoming light and the resistance of the cell changes. This change in resistance is then used to create an electrical signal that can be read and adjusted within the system.

The working principle of the PDV-P8107 is fairly straightforward. When the incoming light level is above the specified range, the CdS cell absorbs more photons and increases its resistance. This increased resistance creates a stronger electrical signal, which the system then uses to increase the level of output. Conversely, when the light level is below the specified range, the CdS cell absorbs fewer photons and the resistance decreases. This decreased resistance signals the system to reduce the level of output.

The PDV-P8107 is designed to operate between 0.001 and 0.100 lux. It has three different output levels: 0, 1, and 2.0 lux. The level of output is adjusted depending on the incoming light level detected by the CdS cell. If the light level is above 0.100 lux, the system will switch to the maximum output level of 2.0 lux. Likewise, if the light level is below 0.001 lux, the system will switch to the minimum output level of 0.0 lux.

The PDV-P8107 is a reliable and versatile optical sensor that can be used in a variety of applications. It can be used to detect and adjust light levels in indoor and outdoor lighting systems, surveillance systems, and tracking systems. It is also easy to install and can be powered using a standard power source. The CdS cell ensures accurate and reliable readings, making the PDV-P8107 an ideal choice for many sensing applications.
