Hello everyone,
I’m starting a new project with ultrasonic sensors HC-SR04 (these are that I have get) and only interesting me use the emitter of these. And as I’m not so good in Acoustic, I need help or some advice that be useful.
I have investigated about the ultrasonic sensors that I’ll use and I have seen information of its characteristics and the way of operation they. The problem to which I confront is that I need to one way increase the operation angle in which operates this sensor, due to the HC-SR04 only works about 15 degree. What I want to do it is by a microcontroller, I can to be manipulating the emitter of HC-SR04, which will be collocating in a permanent point and that it works like radio antenna, and that I from any place within a specific range can catch with the receiver the signal that emitted this.
If someone has an idea how I could solve it, would be great, or if someone know any other type of ultrasonic emitter also leave me the link of the data sheet.
