Screen off when proximity sensor covered?

[Pinmac1]

I have tried a few apps for this from Google Play but none has been quite right. I have a flip cover on my Galaxy Note and would like the screen to go off when the proximity sensor is covered by the flap and back on when it is opened. But if there is no delay then it goes off accidentally too often when my hand strays too near the sensor.
I feel that I should be able to achieve this in Tasker but I can't find the control for the proximity sensor. Can anyone help please?

Thanks for that, I had found it but couldn't make sense of it and wasn't sure if iw was something else. I have chickened out and splashed out(!) 81p on the pro version of Smart Screen Off which is configurable and does what I need. Sometimes, life's too short.......
