TSOP31138 Application Field and Working Principle

Introduction

The TSOP31138 is a type of infra-red (IR) remote receiver module that is commonly used to control a variety of applications through the remote control. It is a very popular design due to the low cost and reliability, and is used in many electronics projects such as remote control systems, home automation, and industrial control. This article will analyze the various application fields of the TSOP31138, as well as its working principles.

Optical Sensors - Photo Detectors - Remote Receiver

The TSOP31138 falls within the category of optical sensors, which can be further divided into two types: Photo Detectors and Remote Receivers. A photo detector is a device that captures and measurements light, and converts it into electrical signals. These signals can then be processed and used to control many different applications. A remote receiver is a type of photo detector, specifically designed to receive signals from remote control devices. It contains an integrated IR receiver and amplifier, specifically designed to demodulate and process the signals from these devices.

Application Fields

The TSOP31138 is used in a variety of applications, most notably in remote control systems. It is often used as the receiver module in these systems, and is responsible for receiving and processing the signals from the remote controller. It can be used for controlling televisions, air conditioners, home automation systems, and other electronic devices. It can also be used for industrial control and robotics applications.The TSOP31138 can also be used as an input device in data acquisition systems. In these systems, it can be used to sense switches, and convert the inputs into electrical signals, which can then be processed and used to control automated systems.

Features

The TSOP31138 is a highly versatile module, and has several key features. Firstly, it has a wide receiving range, and can receive signals from up to 10 meters away. Secondly, it has an automatic gain control system, which helps to eliminate interference. Thirdly, it has a high signal-to-noise ratio, and can detect signals even in noisy environments. Finally, it has a low power consumption, and can operate on voltages ranging from 1.5V to 5V.

Working Principle

The TSOP31138 is designed to receive and demodulate signals from remote control devices. When a command is sent from the remote control, the receiver will capture the IR radiation in the form of a pulsed signal. This signal is then amplified and filtered, before being sent to the microcontroller for processing. The microcontroller processes the signal and converts it into a logic level signal, which can then be used to control the device.

Conclusion

The TSOP31138 is a popular type of infra-red remote receiver module, and is used for controlling a variety of applications. It is highly versatile, and has a wide range of features including a wide receiving range, automatic gain control, a high signal-to-noise ratio, and low power consumption. Additionally, it has a well-defined working principle, and is able to accurately receive and process signals from remote control devices. Its various features and broad application fields make it a popular choice for electronics projects.
