I am working on a project in which I have to use ultrasonic sensors HC-SR04. I need to know how can determine the number of sensors that is separate in the circumference to coverage area (such as 40cm * 100cm) ? And how can get the ideal location among each sensor in this area? "the picture which I attach just to show what i need as example" example about what i need
You need only 3 sensors, as in your example the location of S3 and S4 is okay, put only 1 more sensor in front location in the middle point of S3 & S4 ( opposite face ) . I have exactly as this project, but i need to programs these 3 sensors with some algorithm to distribute them in a scientific forms Good Luck
