I recently got a EDP SonaSwitch sonar and started testing it yesterday.
The trouble is, all the web documentation on it is fiendishly vague, and it barely gives me enough instructions to keep from damaging it. To give you an idea, the official data sheet is only 1 page long. I'm writing some µcontroller code to test it, but it is all trial-and-error at this point. I was hoping someone here might have some advice on it, or at least a link to a more detailed guides or a schematic...anything.
Also, when I power up the sensor I can hear a rapid clicking that is obviously out of the ultrasonic range. Is this typical for ultrasonic sensors, or is it fried? It's described as an "electrostatic transducer" with a repitition rate of 10Hz (astable). The clicking I'm hearing seems much closer to 3 or 4 Hz though.
