Optical Sensors - Phototransistors cover a wide range of applications, from measuring the intensity of light to sensing the presence of people or objects in a specific area. The QSB320 phototransistor is a light-activated semiconductor switching device designed to provide reliable performance in a variety of applications requiring sensing of infrared (IR) light sources. This phototransistor is available in a variety of packages, from standard through-hole to surface-mount.

The QSB320 phototransistor works by using an internal infrared-detecting diode to sense and convert the light into an electrical current. This current is then amplified and converted into a usable output signal. When a light source is present in the detection area, the phototransistor will generate a high output signal, which can be used to turn on an LED or activate a relay, for instance. Different versions of the QSB320 are available, optimized for infrared light with wavelengths anywhere from 760 to 850nm.

The QSB320 can be used in a variety of applications, including motion sensing, door and window interlock detection, smoke and gas detection, and as an optical detector integrated into digital camera and camcorder systems. It is also used in energy-saving applications, such as occupancy sensing systems and Voice-over-IP (VoIP) telephone systems. As mentioned before, the QSB320 is particularly useful for infrared detection, due to its optimized wavelength range.

In addition to its broad range of applications, QSB320 phototransistors offer several advantages over other types of sensors. They are able to operate at a wide range of temperatures and are not affected by external light sources. They typically require low power consumption, and are also durable and resistant to vibration or shock. Most importantly, the QSB320 is sensitive to even the smallest amount of light, which makes them ideal for detecting objects or people in dark or dimly lit rooms.

The QSB320 is an incredibly versatile and powerful sensor that can be used for a wide range of applications. By utilizing its IR detection capabilities, power efficiency, and durable design, it can be applied to virtually any project or system requiring optical sensing. Its strong performance and reliable performance makes it a great choice for any project requiring sensing of IR light sources.
