HX1838 Infrared Remote Control Transmitter and Receiver Kit

The Infrared Remote Control Kit is a widely used tool in electronic projects and remote control systems. It transmits and receives signals quickly and accurately using infrared technology. This kit includes an HX1838 Transmitter and Receiver, where the transmitter sends digital signals via an infrared LED, and the HX1838 Infrared Remote Control Transmitter and Receiver Kit processes these signals for precise control.

The kit is recognized as an infrared remote control system, and the receiver section contains a PIN diode and a preamplifier circuit mounted on a single frame inside a durable epoxy package. This design protects the module against light noise and electrical interference, ensuring high-precision signal detection. The module supports operating voltages from 3.3V to 5V, and the input pin can be connected directly to a microcontroller with a 10KΩ pull-up resistor.

The 38kHz Infrared Receiver Module in this kit features a built-in PCM frequency filter to eliminate ambient light noise. It also includes internal protection against electromagnetic interference, improving signal stability and quality. With an operating voltage range of 3.0–5.0V and full compatibility with TTL and CMOS circuits, this module is highly versatile.

Operating at 38kHz, the receiver can detect signals from 5 to 8 meters, making it ideal for various remote control applications. The kit includes an infrared remote, the HX1838 Infrared Wireless Remote Control Kit, and a 3-pin, 20cm cable. This setup, often referred to as a digital infrared remote control board, allows for quick and easy implementation of remote control systems.

Due to its stable performance under varying lighting conditions, this product is widely used in home automation, robotics, and digital device control projects. Operating at 5V, the 5V Transmitter and Receiver kit is an ideal choice for electronics enthusiasts and developers looking for precise, high-quality remote control system solutions.

Educational Note:
IR receivers are diodes whose resistance changes with the intensity of infrared light in the environment. Infrared light is invisible to the naked eye but can be detected with digital cameras. Since sunlight and other sources emit high levels of infrared light, interference may occur. Therefore, the transmitter and receiver must operate at a specific frequency to avoid noise.
