Ultrasonic Distance Transducer – HY-SRF05
Meet the HY-SRF05 – a longer range, more precise ultrasonic sensor. These sensors use a pulse of ultrasonic sound and listen for a response. Since the speed of sound is relatively stable, we can measure the time between the pulse and the echo to determine distance.
We have found this version to be quite a bit better at detecting objects at longer distances than the HC-SR04. The SRF05 will detect a person sized object out to approximately 4 meters; walls and other large flat surfaces can be measured over 5 meters away!
These sensors are not pin compatible with the HC-SR04, as there is one extra pin. These are, however, code compatible with any of the HC-SR04 examples out there.

watch out for the dimensions, the distance of the two cylinders is a bit smaller than in the original hc-sr04, so they do not fit into some of the mechanical holders!
