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:
- Compatibility: Arduino UNO R3 / Arduino Mega2560 and other microcontroller board
- 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
