5PCS OPEN-SMARTIR Emitter Infrared Transmitter Module with 38K Hz Carrier OnBoard for Arduino

Description

Note: Use the board that has upload the NEC protocol program, The remote control distance can reach about 6 meters, and with the angle of the transmitting and receiving module aligned, the remote control distance may reach up to 8 meters.

This is infrared transmitter module based on NE555. 38KHz carrier circuit is produced by the NE555, no MCU's PWM pins, reduce the corresponding codes and the burden for MCU.

When SIG module pin is at high level, the module will send an infrared signal of 38KHz. When SIG pin is at low level, the module will stop sending infrared signal;

The usage is very simple, so the ordinary MCU can be also used to easily produce infrared remote control projects.

Features

- Compatible for Arduino.

- Operating voltage: 4.5 ~ 5.5V DC

- Operating current: 50mA (max)

- Emission angle: 45 degrees

- SIG pin current: High lelel 0.4mA (max), low level 1.4mA (max)

- You can manually adjust the direction of the launch tube according to the actual application requirements

- Great for infrared remote control projects
