Difference b/w Ultrasonic Transduer pair and module
I was wondering if I could use an Ultrasonic Transducer pair (like this one ) instead of an Ultrasonic module(module recommended online by anonymous).
I don't need to calculate distance for a robot car or anything,I just need to transmit and receive signals from the sensor,If i select the module I still need to unsolder the Transmitter sensor and wire so that i can hold it in my hand to transmit and the receiver on the other hand to receive signals and process tunes on varying distance by 3.5 mm output ............
Is it possible to use the transducer pair instead of the module ??
what are the differences b/w a sensor module and the transducer pair ??
