Thank you. I will test it and let you know. I might change it to a different sensor if this one is not going to be reliable. It might work if it has a shield to blog the sun rays. It will also depends on the direction and position of the sensor. Either way I will post my results here. I know vandalism and other factors might be a problem also cars and other vehicles going over the shoulder might hit the sensor. Putting the sensor on top of the fence or tree might be too far. Thank you again.
