HY-SRF05 or HC-SR05 Precise Ultrasonic Distance Measuring Transducer Sensor Module
The SRf05 ultrasonic range sensor detects objects in its path and can be used to calculate the range to the object. It is sensitive enough to detect any object around 3 cm to 3 m range.
This module can be used in two different modes:
1. Output pin - single micro-controller pin
2. Dual pin - given a 10uS trigger to the trigger pin and calculating the echo time.
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, this can measure the time between the pulse and the echo to determine distance.
It is 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!
