Infrared Remote Control Module With Receiving Head HX1838 NEC Coding

Description:

Sensor using HX1838, high sensitivity working voltage: 5V Output format: Digital output

Module interface:

VCC external 3.3V-5V voltage (can be directly connected with the 5V MCU and 3.3V chip) GND external GND IN external microcontroller I/O port, I/O port has been designed with 10K pull-up resistor Theoretical test suite from 5-8 meters, but the surrounding environmental factors depends on when you use the actual application and intermediate barrier (e.g. diaphragm, glass, hinder the barrier or other materials), receiving head using HX1838, with a power indicator light, can receive the 38K frequency of any remote control coding data!
