产品介绍:
PING)))超声波感测器 这是一款搭配BASIC Stamp微处理器所推出的sensor,当然,其他微处理器(51、AVR、PIC、MSP430、ARM)也都可以使用。非常适合使用在机器人上,可以检测移动中或静止的物体,使用时只要微处理器的1个I/O即可。 PING))) sensor使用发出超音波(远超过人所可以听到的频率),从sensor到待测物,由接收回波所需要的时间来判断距离。 PING)))发出的是一个PWM(脉冲宽度调制)的脉冲信号,接收也是PWM信号。
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.
