HX1838 Infrared wireless remote control Kit Remote control module remote control receiver board

Product Introduction

The latest infrared wireless remote control kit consists of a Mini ultra-thin infrared remote control and a 38KHz infrared receiving module. The Mini ultra-thin infrared remote control has 17 function keys and a transmission distance of up to 8 meters, making it very suitable for controlling various devices indoors. The infrared receiving module can receive standard 38KHZ modulated remote control signals. By programming, the remote control signal can be decoded, thus making various remote control robots and interactive works

Product Parameters

Static current: 3-5uA

Dynamic current: 3-5mA

Surface material: 0.125mmPET, effective life 20,000 times

Transmitter infrared wavelength: 940Nm

Crystal frequency: 455KHZ crystal

Carrier frequency: 38KHZ

Encoding: The encoding format is NEC

Remote control size: 86*40*6mm (length*width*height)

Product Description

Module interface description

1. VCC external 3.3V-5V voltage

(can be directly connected to 5V MCU and 3.3V MCU)

2. GND external GND

3. IN external MCU I/O port, 10K pull-up resistor is designed for I/0 port

Note

The theoretical test distance of the kit is about 5-8 meters, but the actual application depends on the surrounding environment factors and intermediate obstacles (such as diaphragms, glass, obstacles or

other materials when you use it). The receiving head uses HX1838 with a power working indicator light,

which can receive data of any remote control code at 38K frequency
