Optical sensors are devices that convert optical energy from a source such as light or infrared radiation into another form of energy, such as electrical or mechanical energy. Photo detectors are a type of optical sensor that uses a light-sensitive material to detect changes in light intensity or color components. A remote receiver is a type of photo detector that receives and processes infrared light signals originating from external sources, such as remote control handsets. In this article, we will discuss one particular type of remote receiver: the TSOP34738.

Application Field

The TSOP34738 is a general-purpose remote receiver typically used in digital television and audio/video equipment, such as TVs, DVD players, and set-top boxes, among many other consumer electronic products. It is also widely used in remote control systems, as it is capable of operating across a wide range of light frequencies from one single sensor.

In addition to its use in remote control systems, the TSOP34738 is also popularly utilized in proximity sensing, motion sensing, and gesture recognition. In these fields, it is used to detect the presence of an object or motion nearby. This can be useful, for example, in automatic doors, allowing them to open and close according to the presence of an individual in the vicinity.

Finally, the TSOP34738 is also found in various industrial applications, such as factory automation, mining, and continuous process monitoring.

Working Principle

At the heart of the TSOP34738 is an infrared receiver diode. When light of a particular frequency is detected, the diode generates an electric current. This current passes through an amplifier to increase its strength, and the output is used to drive either an analog or digital circuit.

The frequency of the light that the TSOP34738 detects can be tuned in order to match the frequency of the receiver\'s light source. This ensures that only the desired signal is received while spurious signals are ignored. The TSOP34738 can detect frequencies ranging from 38kHz, the standard for many remote control systems, to 55kHz.

In addition to being sensitive to IR light, the TSOP34738 has other features that make it advantageous to use over other types of receivers. It has a wide dynamic range, meaning that it can operate effectively in various lighting environments, from strong sunlight to near-darkness. It also has a fast response time, which ensures that signals are received and processed promptly.

Finally, the TSOP34738 is available in a range of sizes, from 3mm up to 4.5mm, meaning that it can be conveniently fitted into a variety of housing sizes. This makes it possible to use the TSOP34738 in compact designs with relatively small housing environments.

In summary, the TSOP34738 is a versatile remote receiver that is commonly used for remote control systems, proximity sensing, motion detection and gesture recognition. Its ability to detect a wide range of light frequencies, its wide dynamic range and its fast response time make it suitable for a wide variety of consumer and industrial applications.
