IMPORTANT
Where is the IR sensor placed ?
Added after 1 hours 59 minutes:
I see what you got there ,a simple
TX Infra red Led that has its beam broken by the operator
A child could put that together.
Most probably the beam is not set properly.
I see an other Led ,looks as it is used to set the beam
The intensity of the beam might be too low or too strong and reflects on the walls.
If you pay 3000.00 for that it should be cents .....
Sad....
