Infrared remote control receiver module — Model VS838 Key benefits Reliable infrared reception up to 15 m, enabling responsive remote control in typical home and commercial environments. Wide operating voltage range (2.7 V to 5.5 V) for straightforward integration into a variety of low-voltage systems. Compact footprint (7 x 6 x 5.4 mm) that saves board space and fits tight enclosures. Clear logic-level signaling with defined low and high voltages (Low: 0.4 V, High: 4.5 V) for predictable interfacing with external electronics. ±45° receiving angle provides stable reception when the transmitter is pointed within a conventional remote-control cone. Main features and specifications Product name: Infrared remote control receiver module Model number: VS838 Working voltage: 2.7 V to 5.5 V Reception distance: 15 m Receiving angle: ±45° Low level voltage: 0.4 V High level voltage: 4.5 V Body size: 7 x 6 x 5.4 mm (L x W x D) Function: Infrared signal reception for remote-control applications Why customers need this module Simplifies adding IR remote capability to devices without bulky components or complex circuitry. Compatible with a variety of low-voltage systems because of its 2.7–5.5 V operating range. Small package reduces mechanical design constraints and supports compact product designs. Defined output voltages improve compatibility with other logic devices and reduce integration guesswork. Practical use scenarios 1) Consumer electronics retrofit: Add remote control reception to a speaker, set-top accessory, or LED controller where a 15 m range and ±45° acceptance are sufficient. 2) Compact embedded projects: Integrate the VS838 into compact control modules where board space is limited and a stable IR receiver is required. 3) Remote-controlled appliances: Use the module in small appliances or toys that require reliable IR reception within a typical room-sized range. Integration notes Ensure supply voltage is kept within 2.7 V to 5.5 V for correct operation. Orient the module so the transmitter is within the ±45° acceptance cone for best reception. Expect logic outputs near the specified low (0.4 V) and high (4.5 V) levels for interfacing decisions. The VS838 infrared receiver module delivers compact size, predictable electrical levels, and practical range for straightforward integration into remote-control applications.
