Hi all,
I am working on an ultrasonic sensor for occupancy sensing. This device would drive an LED based on movement, and I was wondering if detection could be achieved the following way
Where the sensors and the moving person lie in opposite sides of the wall, and the ultrasonic waves would ultimately travel from the moving person onto the Ultrasonic receiver for processing.
Has anyone heard of this or implemented it? I just want to know if it is possible with any low grade transducer.
