TSOP4140 is a type of remote receiver used in optical sensors. It is a two-pin, low-power and highly sensitive receiver, which excels in short-range communication. This particular product, as with other remote receivers, is essential for proper functioning of a number of electronic systems.

The application possibilities of the TSOP4140 fall into two main categories: home automation and industrial control systems. Home automation systems focus on optimising comfort, convenience, and safety of the home environment. These range from turning on lights at the touch of a button, locking doors automatically, or adjusting air temperature, to more complex functions such as controlling home theatre systems. The TSOP4140 is ideal for these applications, as it can be used to control multiple electrical appliances from a single remote control.

Industrial control systems on the other hand, are wide-reaching applications used in the industrial, commercial, and governmental sectors. These consist of almost anything from controlling machinery in a factory, to managing various security systems and managing a complex power grid. Generally, high power and long range are the most desired characteristics of receivers for industrial purposes, and the TSOP4140 does not disappoint. With its reliable working range of around 7 meters, it caters to all these requirements.

The working principle of the TSOP4140 revolves around its sensitive – yet powerful – optical receiver system. The receiver is connected to a demodulator, which is used to signal processing. The signal is then passed through a preamplifier, followed by a band-pass filter ranging from approximately 10KHz to 40KHz. These frequencies are within the range of standard remote controllers. The final output signal is monitored through an activated transistor. This all happens very quickly – generally within 0.43 milliseconds – which makes it suitable for applications where fast response is crucial.

In summary, the TSOP4140 is a highly versatile two-pin remote receiver. Its features make it the ideal solution for electronic systems requiring reliable short-range communications. It has applications in both home automation and industrial control systems, and is able to operate within a wide range of frequencies. Given its low-power and fast response, it is no surprise that the TSOP4140 is gaining recognition as one of the premier remote receivers on the market.
