1 Set IR Remote Kit for Arduino Raspberry Pi, 38kHz Infrared Receiver Module 3.3V/5V, 8m

HX1838 Infrared Receiver Module DIY Kit Description A compact, high-sensitivity infrared receiver module based on the HX1838 sensor designed for easy integration with microcontroller projects. The module provides reliable 38 kHz IR signal reception, a digital output, and a built-in pull-up resistor for straightforward connection to common development boards. Key benefits - Easy integration: Works directly with 5 V and 3.3 V microcontrollers without additional level shifting, simplifying hookup to Arduino and Raspberry Pi projects. - Reliable signal reception: HX1838 sensor tuned to 38 kHz decodes standard remote control signals for remote learning and control tasks. - Low power usage: Very low standby current and modest active current help keep overall system power consumption down. - Ready to use: Digital output and an onboard 10 k pull-up resistor on the input make the module plug-and-play for many applications. - Practical range and angle: Designed for typical remote-control distances and a practical reception angle for home and hobby use. Technical specifications - Sensor model: HX1838 high-sensitivity IR receiver. - Operating voltage: VCC 3.3 V to 5 V compatible with 3.3 V and 5 V microcontrollers. - Output form: Digital output. - Built-in pull-up: 10 k pull-up resistor on the I/O input for direct connection to microcontroller pins. - Receive frequency: 38 kHz carrier. - Typical reception distance: up to 5 to 8 meters depending on environment and signal obstacles. - Effective reception angle: about 60 degrees. - Quiescent current: approximately 3 to 5 uA. - Operating current: approximately 3 to 5 mA when active. - Power indicator: onboard LED shows reception activity. - Remote battery: uses CR2025 coin cell for the transmitter when applicable; battery not included. Compatibility and connection notes - Compatible with common development platforms such as Arduino and Raspberry Pi for remote decoding and control tasks. - Connect VCC to 3.3 V or 5 V, GND to ground, and the module output to a microcontroller input pin. The onboard pull-up resistor reduces the need for external components. - Performance depends on environmental factors and obstacles such as glass, membranes, or other materials that may block IR signals. Typical use scenarios - Remote control decoding: Capture and decode consumer remote control codes for custom automation or learning remotes. - DIY home automation: Use as an IR input for media centers, IR-controlled lights, or remote-triggered devices. - Robotics and prototypes: Add remote control capability to robots and prototype systems without complex hardware changes.
