Specifications

• Infrared remote control distance: more than 8 meters
• Launch tube infrared wavelength: 940Nm
• Crystal frequency: 455KHZ crystal
• Carrier frequency: 38KHZ
• Encoding: encoding format for the NEC
• Size: 86 * 40 * 6mm
• Power: CR2025/1600mAH

Use

Remember that the remote control and the ir receiver is a set, it has to decode the code and will display a hex code.

Test

• Arduino controller × 1
• USB data cable × 1
• Infrared remote control × 1
• the infrared receiver module × 1

Schematic

• Arduino GND --> Module pin -
• Arduino +5V --> Module PLUS (middle pin)
• Arduino Digital pin 11 --> Module S

Raspberry Pi2

Tutorial

Wiring the pi with the module

1. left pin (GND) to pin 6 (GND)
2. Center pin (VCC) to pin 1 (3,3V)
3. Right pin (DATA) to pin 12 (GPIO 18)

Setting up Raspbian

Before running any code, install LIRC with sudo apt-get install lirc and the follow the prerequisites below

edit /etc/modules and add the lines below:

1. lirc_dev
2. lirc_rpi gpio_in_pin=18 gpio_out_pin=17

edit /etc/lirc/hardware.conf and modify to add the correct values as below:

1. DRIVER="default"
2. DEVICE="/dev/lirc0"
3. MODULES="lirc_rpi"

edit /boot/config.txt and edit the dtoverlay value like this:

1. dtoverlay=lirc-rpi,gpio_in_pin=18,gpio_out_pin=17,gpio_in_pull=up

reboot your pi

after reboot:

1. stop lirc daemon: sudo /etc/init.d/lirc stop
2. test your ir receiver by running: mode2 -d /dev/lirc0 then by pushing any key on your remote to see if something happens (random numbers)

your IR receiver is working !
