I want to use this as a part of a larger project
any idea how can i redirect the output to serial?
It is possible to redirect the serial output. You would need to make minor modifications to the firmware. I think this would primarily involve changing "Serial" in SerialReceiver.cpp and SerialHandler.cpp to the new serial port. The Uno only has one hardware serial port (pins 0 and 1) which is used for USB serial, but you could use SoftwareSerial (https://www.arduino.cc/en/Reference/softwareSerial) to make any two digital pins into a serial port.
