Description:

HC-SR04 Ultrasonic Range Finder Distance Measuring Module Sensor Arduino Pic UK

How to:

Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not.The out pin of this module is used as a switching output when anti-theft module, and without the feet when ranging modules.

Note : the module should be inserted in the circuit before been power, which avoid producing high level of misoperation;if not, then power again.
