產(chǎn)品介紹：

PING)))超聲波感測器 這是一款搭配BASIC Stamp微處理器所推出的sensor,當(dāng)然,其他微處理器(51、AVR、PIC、MSP430、ARM)也都可以使用。非常適合使用在機(jī)器人上,可以檢測移動中或靜止的物體,使用時只要微處理器的1個I/O即可。 PING))) sensor使用發(fā)出超音波(遠(yuǎn)超過人所可以聽到的頻率),從sensor到待測物,由接收回波所需要的時間來判斷距離。 PING)))發(fā)出的是一個PWM(脈沖寬度調(diào)制)的脈沖信號,接收也是PWM信號。

Parallax's new PING)))?

• ultrasonic sensor provides a very low-cost and easy method of distance measurement. This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects. Naturally, robotics applications are very popular but you'll also find this product to be useful in security systems or as an infrared replacement if so desired. You will definitely appreciate the activity status LED and the economic use of just 1 I/O pin.




• The PING))) sensor measures distance using sonar; an ultrasonic (well above human hearing) pulse is transmitted from the unit and distance-to-target is determined by measuring the time required for the echo return. Output from the PING))) sensor is a variable-width pulse that corresponds to the distance to the target.




• Interfacing to the BASIC Stamp and Javelin Stamp microcontrollers is a snap: a single (shared) I/O pin is use to trigger the Ping sensor and "listen" for the echo return pulse. And the intelligent trigger hold-off allows the PING)))? to work with the BS1! An onboard three-pin header allows the PING))) to be plugged into a solderless breadboard (on a Boe-Bot, for example), and to be connected to its host through a standard three-pin servo extension cable.
