I was wondering how many of these Ultrasonic Module HC-SR04 Distance sensors I can connect to one Arduino Uno Board?
I wasn't sure if it was 14 since the Arduino uno has 14 digital outputs.
I'm not an electronics person, but I'm hoping there is a clean and easy way to connect the sensors to the board via some standardized connectors.
Will I be able to power the device and all distance sensors via USB connected to my PC?
Also does anyone have experience with the sensor? I am wondering what the min and max measuring range of the sensor is and how long it takes for it to be able to provide an accurate reading.

ya plus the analog pins configured as outputs.

some centimetres, check out the datasheet, i tried to check the datasheet but my connection is slow so wasn't able to load it.

USB port on your laptop or pc regardless of which OS you are using provides 5v @ 500 mA and the many sensors you propose to use bill put a power surge issue on your computers USB port, just connect the grounds of arduino + sensor + external battery source and power them from external power.
