The HS0038S4TT is an infrared remote control receiver module manufactured by Vishay. These modules are designed to receive modulated infrared (IR) signals, commonly used in remote control applications. They integrate a photodiode, preamplifier, and demodulating circuit into a single package.

Applications

• Infrared remote control systems for TVs, DVD players, and other consumer electronics.
• Remote control for lighting systems.
• Wireless control of toys and other devices.
• Industrial control systems using IR communication.

Features

• Excellent noise suppression due to internal filter for PCM frequency.
• Low supply current.
• Photo detector and preamplifier in one package.
• Internal filter for PCM frequency.
• TTL and CMOS compatibility.
• High immunity against ambient light.

Benefits

• Simplified design: Integrates all necessary components for IR signal reception, reducing the number of external components required.
• Improved performance: Optimized for reliable IR signal detection, even in noisy environments.
• Lower power consumption: Designed for low power operation, extending battery life in remote control applications.
• Compact size: Small package size allows for easy integration into space-constrained designs.

Additional Details

The HS0038S4TT operates at a carrier frequency of 38 kHz, which is a common standard for IR remote control systems. The output of the module is an active low signal, meaning that the output is low when an IR signal is detected and high when no signal is present. The module requires a supply voltage of typically 5V and has a typical reception range of up to 10 meters, depending on the strength of the IR signal. This device is RoHS compliant, ensuring it meets environmental standards for hazardous substances.
