I am using a tsop 1738 ir receiver . I am not using any library that is available for the sensor on the internet and am directly connecting the terminals of the sensor to the uno,but i am not getting the low state when i am using a remote.I am using the standard digital read library example in the uno for reading the data.i haven't connected any passive components as well in my connection to the arduino.

So what code are you using? Post a photo of how you have wired it up.
