You might be probably thinking that this question has been answered a thousand of times, but I think this case is different.
I bought a couple of days ago a ultrasonic sensor from Conrad with the following reference:
ULTRASONIC SENSOR K-14WP10 http://shop.conrad-uk.com/components/sensors/ultrasound-sensors/182271.html
I was expecting this sensor to be same as the rest of the ultrasonic sensor examples I've found but this is not the case, this sensor has only two wires, while the rest of the examples three wire sensors which confuses me a bit.
The spec data sheet does not have many details si I'm a bit without much ideas from where to start from.
Maybe you guys are able to provide me some guidance on where to start from. I swear I've googled but most probably I'm not issuing the correct words.
Thanks in advance.
