KontroLIR – 100% Arduino compatible IR remote Control, with optional extras

work in progress


Where To Purchase

KontroLIR is available in our store and can be purchased via Buy KontroLIR.

KontroLIR is comprised of twin modules, one for Tx and the other for Rx. It is also possible to use the Tx module as a 38kHz IR transmitter and the Rx module as a general purpose 38kHz IR receiver.

Data Sheet

The data sheet can be found by clicking here

Applications

KontroLIR, can be used in the following:

  • Light Barriers
  • Security projects
  • Lap Timers


BeamIR can be used in both 'beam mode' where the 2 modules are placed at either end of the invisible beam and in 'reflective mode' where the IR is bounced or reflected off a target and both modules are placed side by side facing the target.

KontroLIR Pin Out Serial Interface

Serial interface pinout

The header pins for the Serial I/F interface are laid out as follows:

  • GND -ve supply power Ground / 0V
  • TXD Connects to TXD on the adapter (Connected to TXD0 on the ATmega328PB)
  • RXD Connects to RXD on the adapter (Connected to RXD0 on the ATmega328PB)
  • VCC +ve supply power 5V (will also work with a 3V3 supply @ 8MHz or 4MHz)
  • RTS Used to reset the MCU during Firmware upload
  • DBG Unpopulated by default. Can be used as a debug pin, if necessary. Also connected to the LED.


Note 1: The image is looking from the keypad up. Looking throught the battery compartment, the order will be mirrored.

KontroLIR Pin Out ICSP

Serial interface pinout

The header pins for the AVR ICSP interface are laid out as follows:

  • GND -ve supply power Ground / 0V
    • MISO Standard ICSP pin for use with avrdude & USBASP, Atmel ICE programmer or equivalent
    • RESET Standard ICSP pin for use with avrdude & USBASP, Atmel ICE programmer or equivalent
    • SCK Standard ICSP pin for use with avrdude & USBASP, Atmel ICE programmer or equivalent
    • MOSI Standard ICSP pin for use with avrdude & USBASP, Atmel ICE programmer or equivalent
  • VCC +ve supply power 5V

Basic Functionality

Whne a Tx & Rx module are configured correctly and operational the outputs will be as follows:

IR Beam not broken

  • OUT => Logic LOW (Close to 0V)
  • OUT2 => Logic HIGH (Close to VCC, via pull-up resistor)
  • OC => Open Collector, shorted to GND via NPN/CE (Driven by OUT2)
  • Red LED => ON

IR Beam broken

  • OUT => Logic High(Close to VCC)
  • OUT2 => Logic LOW(Close to GND, via NPN/CE)
  • OC => Open Collector, Open & connected to NPN collector, which is 'turned off'
  • Red LED => OFF

Range

The effective range of BeamIR can be from 1m to 20m+ depending on the IR Power setting and ambient lighting. However, it is important to note:

  • The further the range the wider the IR Beam, So it may help to reduce the beam width, by using an opaque pipe for direction.
  • Sunshine can interfere with IR transmission. The carrier frequency helps mitigate errors due to sunshine. Pulsing the Tx module at say 600uSecs can help distinguish between valid beam signals and interference.
  • If sunshine is a factor, placing the receiver unit on the side pointing away from the Sun, will help.
  • Much longer ranges and narrower beams can be achieved by the use Optics/lenses to focus the beam.

Configurations

It is possible to use BeamIR in various configurations

  • 5V or 3V3 mode
  • x1, x2, x3 or custom IR Power
  • As a 38kHz IR emitter (Tx Module)
  • As a general purpose IR receiver (Rc Module). Excellent performance across multiple IR protocols & carrier Frequencies.
  • Using Logic Lever or OC output.
  • Multiple Rx modules with a single tx module
  • Combination of multiple Tx & Rx modules (e.g. virtual fence enclosing an area)
  • With optics and/or shielding (Pipes/light barriers) to improve range & performance.
