Optical Sensors - Photo Detectors - Remote Receiver

The TSOP33456 is a type of optical receiver which provides signal reception for infrared remote control systems. It is a photo detector designed to detect infrared radiation from remote control transmitters and process signals from these transmitters to allow for various remote operations. This type of remote control system is commonly used for consumer appliances, such as TVs and other home electronic devices.

Application Field

The TSOP33456 is used in a variety of applications. These include remote control receivers for TVs and other consumer products, as well as remote control systems for applications in industrial automation and robotics. In terms of wireless control projects, this type of infrared remote receiver is often used when robust and reliable performance is needed.

Working Principle

The TSOP33456 consists of a PIN-diode and an integrated preamplifier which amplifies the received infrared signal. This signal is detected by an inbuilt integrated circuit and the output is a logic level signal which can then be connected to the required microcontroller. The working principle of the device is relatively simple. When the receiver is exposed to infrared radiation, the PIN-diode begins to conduct and the amplification of the signal is processed by the integrated circuit. When the radiation is of a sufficient strength, the output signal is triggered and can be used for remote control operations.

The TSOP33456 is designed for use with 38 kHz carriers and is sensitive to only to signal modulated at that frequency. This feature helps to ensure reliable signal reception and reduce interference from other devices.

Conclusion

The TSOP33456 is a type of optical receiver designed to detect and process infrared radiation from remote control devices. It is commonly used in a variety of applications, ranging from consumer products to industrial automation and robotics. The device operates by detecting the infrared radiation and amplifying the signal which is then processed to produce a logic level output signal. This type of remote control receiver is ideal for environments where accurate detection and reliable performance are needed.
