I'm new to Arduino and this is my problem. I need to track an object in a room. For now I have placed 3 sensors on the edges of each axis (x, y, z), where the x axis will the line between the east and the west walls of the room, the y axis will be the north and south walls of the room, and the z axis will be the ceiling of the room.
I have written code to get the output as x, y, z coordinates. But since the HC-SR04 has no horizontal range it can only track objects in its line of sight. Due to this I'm not able to fulfil my requirements. So I thought if I could couple up an array of HC-SR04s together to work as one sensor I can get more horizontal range.
Is this possible using an Arduino Uno R3? If it's possible, please guide me through it.
