Ultrasonic obstacle sensor module.........750/-
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.
Features:
Provides precise, non-contact distance measurements within a 2 cm to 3 m range
Simple pulse in/pulse out communication
Burst indicator LED shows measurement in progress
20 mA power cosumption
