TSOP34840

The TSOP34840 is a compact infrared (IR) receiver module used primarily for remote control applications. It is designed to detect 38kHz modulated IR signals, a common frequency for remote controls. This module integrates a photodetector and preamplifier in a single package, providing a demodulated output signal that indicates the presence of an IR carrier, facilitating easy interfacing with microcontrollers or logic systems.
Key features of the TSOP34840 include high immunity to ambient light, low power consumption, and a wide angle of reception. It is capable of operating within a wide supply voltage range and responds reliably in various environmental conditions. The module's design includes a metal housing to shield against electrical noise, enhancing its performance and reliability.
The TSOP34840 is used in numerous applications such as television sets, DVD players, and other consumer electronics that require IR remote control functionality. Its ease of use and reliable performance make it a popular choice for developers looking to incorporate IR communication into their projects.

Equivalent products to the TSOP34840 infrared receiver include the Vishay TSOP348 series with different frequencies, such as TSOP34836 (36 kHz) and TSOP34856 (56 kHz). Other alternatives may include components like the Everlight IRM-3638N3 or Sharp GP1UX511 series, depending on the specific requirements like operating frequency, voltage, and angle of detection. Always check the datasheets to ensure compatibility with your application.

The TSOP34840 is a miniaturized infrared receiver module for infrared remote control systems. It typically comes in a 3-pin package. Here's a brief overview of its pin configuration and function:
1. Pin 1 (OUT): This pin provides the demodulated output signal. It outputs a low signal when the IR receiver detects a valid IR signal modulated at a frequency of 40 kHz, which is commonly used in remote controls.
2. Pin 2 (GND): This is the ground pin and should be connected to the ground of the circuit.
3. Pin 3 (VS): This is the supply voltage pin. It is usually connected to a voltage source within the range of 2.5V to 5.5V, allowing compatibility with various microcontroller and circuit voltages.
The TSOP34840 is designed to receive and demodulate IR signals, making it useful for applications such as TV remote controls, air conditioner remote systems, and other IR-based wireless communication systems.
