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 a 10K pull-up resistor. Theoretical test range is from 5-8 meters, but the surrounding environmental factors affect the actual application range and intermediate barriers (e.g., diaphragms, glass, or other materials) hinder reception. The receiving head uses HX1838, and it includes a power indicator light. It can receive 38K frequency data from any remote control with compatible coding!
