Optical Sensors - Photo Detectors - Remote Receiver

Infrared (IR) technology has been used in various applications such as sensors, remote controls and security systems. IR technology generally works by a device sending a signal, and then another device or sensor that receives the signal. As infrared technology continues to be developed, more and more precision has become possible, leading to the increased use of different types of photo detectors and remote receivers. One such device is the TSOP85238AP5TT, a high-sensitivity infrared remote receiver, part of a long product line from Vishay. This article will provide an overview of the TSOP85238AP5TT’s application fields and working principle.

The TSOP85238AP5TT is a monolithic integrated circuit designed for use as a remote receiver in infrared communication systems. It features a high sensitivity of -55dBm, with an output signal high level of 3.6V and a low level of 0.3V. It also has a wide range of operational temperatures (-40 to +70°C), and requires no external components other than a series resistor. The TSOP85238AP5TT can be used to transmit and receive digital signals with a carrier frequency of 38 kHz, making it the ideal choice for projects with an operating frequency range of 30 to 60 kHz.

The TSOP85238AP5TT is suitable for long range communication applications, including remote controllers, voice recognition systems, home automation systems, security systems, and TV remote controls. In these applications, it can detect short bursts of signal and decode it to control an appliance in the area covered by its range. As its frequency range covers a wide variety, it makes it well-suited for many different devices. It is also widely used in consumer electronics such as remote controls for television sets, VCRs, and other electronic home appliances.

The TSOP85238AP5TT\'s working principle is based on the interruption of a focused modulated IR light emitted by an IR transmitter. The modulated IR is received by its antenna and converted to an electrical signal. The electrical signal is then decoded and interpreted by the built-in circuit, and converted into a logical signal which can be used to control an electronic device. As the TSOP85238AP5TT is a highly sensitive device, it can detect IR signals with weak power levels and still deliver a reliable output signal.

Overall, the TSOP85238AP5TT remote receiver is a reliable and efficient device that can be used for a wide variety of applications. Its high sensitivity and wide operational temperature range make it an ideal stand-in for other remote receivers. Its simple operation and minimal external component cost make it an attractive choice for projects that need a highly versatile remote receiver at a reasonable price.
