In figure 1 of the example above we have the area we want to protect. Figures 5 and 6 indicate that the trimpot
adjustment exceeded the limits of the environment to be protected. In this way the microwave will detect move-
ments outside the desired area.
To make it easier to adjust the microwave cover, adjust the trimpot counterclockwise (less sensitive) and walk in
the room you want to protect. Observe the sensor motion detection. If necessary, increase the sensitivity (clockwi-
se). Repeat this process until the sensor only protects the environment where it is installed.
The figure below shows a microwave channel detection range reference.
