	 Arduino High Precision SRF05 Ultrasonic Sensor PWM Out Put Range Finder
	
	Introduction
	- The latest model SRF05. Detection range of 3 cm from the original SRF04 -3 m, increased to 1 cm -4 meters. RF04 is compatible with the original. Also has smaller side lobes.
	- Ultrasonic module can be used to identify obstructions, 1 cm -4 meters. Can be easily connected to the micro-controller, such as BASICX.
	- The ultrasound module will be applied to the robot module. With this module, available in the sonar obstacle within the exact distance. Your robot will be able to bat-like sonar to detect by the surroundings, only a small piece of code, you can obstacles to accurate distance control your motor running, so that your robot can easily of avoiding obstacles.
