As I am new at Arduino, I have been having some problems with using URM04 sensor with Arduino . I have Arduino Uno and I/O Expansion V5.0 . I'm using the code which i got from http://www.dfrobot.com/wiki/index.php?title=URM04_V2.0_%28SKU:SEN0002%29
However I can't read anything from the serial monitor. I tried different bauds (19200 and 115200 ) but still I'm reading strange letters like " Uª".
Can anyone help about using this sensor. I'm not good at programing and just I want to use it simply. I dont need to read temparature, just wanna read the distance.
Thank you Tugsan
