Introduction

An TSOP18356 is an integrated sender-receiver module that aids in the transfer and receiving of wireless data transmissions. An TSOP18356 consists of an infrared (IR) receiver, an IR detector, a preamplifier, a demodulator, and a digital filter, that are all located in a single package. This integrated module helps in interpreting data signals that are transmitted over a variety of carrier frequencies and protocol formats. It is commonly used in a variety of infrared remote-control applications such as remote-controlled toys and security systems.

Application Field

The TSOP18356 has a range of applications that range from toy-based remote controls to security systems. It is commonly used in computers, televisions, audio equipment, remote vehicle systems, remote-control toys, and other household items. The versatile and light-weight module can be used as both a receiver and a sender, making it suitable for use in many different applications.In the case of computer systems, the TSOP18356 can be utilized as an interface between the processor and the external device. This is accomplished by using the IR receiver in the module to interpret signals sent from the external device. The processor can then act on these signals in order to perform tasks such as playing audio or opening doors.The TSOP18356 has also been used in the security market. The module is used to detect the signal transmitted from the remote control of a security system and to alert the security company if the signal is interfered with. The module also aids in override signals, which allow security personnel to remotely open doors in the case of an emergency.For remote-control toys, the TSOP18356 is used to detect the signals transmitted from a remote handset and to interpret them into commands for the toy. For example, the module can detect a signal code for “forward” and can make the toy move in the corresponding direction.

Working Principle

The TSOP18356 works by receiving a signal that is transmitted from the remote sender unit, decoding it, and then acting on it according to the preprogrammed settings. The module is powered by two voltage sources, Vlow and Vhigh, which range from 2.7 to 5.5 volts. The Vlow voltage source powers the receiver part of the module while the Vhigh voltage source powers the transmitter portion.Once the signal is received, the module utilizes an internal filter circuit and a preamplifier circuit to reduce the noise and improve the signal-to-noise ratio. The signal is then demodulated in order to remove the carrier frequency and to extract the useful data. The extracted data is then further filtered by the internal digital filter and is compared to a set of predefined codes programmed into the module. If the code is found, the corresponding command is sent to the processor, which acts on the extracted signal and relays the appropriate responses or data as set by the programmer.

Conclusion

The TSOP18356 is an integrated module that aids in the transfer and receiving of wireless data. The module is commonly used in applications such as remote-control toys, security systems, computer systems, audio equipment, and vehicle systems. It operates by receiving a signal, decoding it, and then acting on it according to the preprogrammed settings. The TSOP18356 is small, versatile, and lightweight module, and it is an ideal choice for a variety of applications.
