Product description: NEC 38 kHz IR remote control + 1838T infrared receiver + module and cables
An infrared remote control with a compatible receiver allows for wireless communication with any microcontroller or kit, including Arduino or Raspberry Pi . A library and software are available on GitHub to facilitate the use of the kit.
Kit with IR remote control and modular IR receiver
This kit allows you to build your own remote control system using an IR remote. An Arduino or Raspberry Pi interfaces with the infrared receiver using a ready-made programming library available on GitHub.
The IR signal's carrier frequency is 38 kHz. The receiver draws a current of no more than 1 mA during operation, and the system's power supply voltage should be between 3.0 V and 5.5 V, allowing it to work seamlessly with both 5-volt systems (Arduino and other AVR-based systems) and 3-volt systems (Raspberry Pi, STM32-based boards, etc.).
Infrared receiver integrated circuit.
Module pinout
| Pin | Description |
|---|---|
| VCC | Module power supply. |
| GND | Mass. |
| IN | Output signal from the receiver. |
Each pin appears twice in the module.
Additional information
The NEC 38kHz IR Remote + 1838T Infrared Receiver + Module and Cables is based on the popular NEC communication protocol, in which bits with a value of "0" are encoded with a sequence of 38 kHz pulses of 562.5µs duration followed by a 562.5µs pause. A logical 1 is encoded with a 562.5µs burst followed by a 1.6875ms pause.
The integrated infrared receiver decodes carrier-frequency pulses while rejecting the vast majority of other signals (including interference from visible light or incompatible IR remote controls). A built-in precision socket allows you to conduct necessary experiments using the module and use the same receiver for permanent soldering into a finished device.
The set includes
- Remote control transmitter
- 1838T Infrared Receiver
- Module for connecting the receiver
- Female-female jumper cables
The set does not include a CR2025 battery , it can be purchased separately.
