Our Friend Martin Todorov has proposed a new beta version of the USB Infrared Transceiver App for Android , that can visualize the received Infrared signals. Martin has contacted us to contribute to the Irdroid USB Project. The new version of the IrdroidUSB Application can be downloaded from the links below:
The USB IR dongle is a USB infrared tranceiver module. It has both transmit and receive infrared functionalities all in one unit.
In Stock / Price : $52$37
The device has 3 powerful infrared LEDs which increases the IR transmit power and widens the transmit angle ( no need to point the device to the target equipment to be controlled). The Device is designed to get its power via the USB / no external power supply is needed . The module has a embedded infrared receiver module for capturing infrared signals @ 38khz frequency (most standard IR remotes work @ 38khz).
Features:
3 High power IR leds for superb transmit range
Infrared Remote Control Decoder
Capture and replay Infrared signals
USB connection to the host system
Supported in LIRC and Winlirc
Open source software and hardware
compatibility with USB IR Toy drivers for linux & Windows
slick transparent USB enclosure
This module works with Winlirc, Lirc and it is part of the Irdroid Wifi unit . The module is powered by the USB bus (5V). The module transmit circuit includes 3 powerful infrared LEDs connected in series. The current flowing through the diodes is constant 100mA. The optical amplifiacation is based on the sum of the optical transmit power mW/Sr of all the three diodes. By using this technique we have increased the transmit range and the transmit angles (this means that the module does not have to be pointed towards the target equipment).
The pic 18F2550 microcontroller is a USB enabled device which is responsible for the transmitter / receiver part of the module, the PC / host communication is via CDC-ACM serial commands. The three infrared diodes are specially positioned one next to other in order to amplify the IR signal and to extend the transmission range. The Infrared receiver IC is located on the PCB bottom side. The Infrared receiver unit is very sensitive and allows adequate IR receiving from a distance of 15 meters.
