Infrared Remote Control Module HX1838 NEC Code

1. Introduction

Containing three 20cm DuPont line
Sensor uses HX1838, high sensitivity
Operating voltage 5V
Output form: Digital output

2. Module Interface Description

VCC: 3.3V-5V external voltage (can be directly connected to the 5v microcontroller and 3.3v microcontroller)
GND: external GND
IN: external microcontroller I/O port, I/O port has been designed 10K pull-up resistor

Kit theory test distance of about 5-8 meters, but the practical application depends on the ambient factors you use, as well as the middle barrier (such as diaphragm, glass, obstructions or other material blocking), receiving head with HX1838 with power work instructions lights, receive 38K frequency any remote coding data!
