Founded in 1995, Kanyuan Optics Product Co., Ltd., is a Sino-foreign joint venture China ultrasonic range finder manufacturer and wholesaler of all kinds of optics products, optical instrument and optical components. All our Oem ultrasonic rangefinder have already been used in many kinds of companies, such as electronic and fine mechanics, medicine, chemical, education, printing, authenticate, lab and science explore. Insisting on manufacturing military and civilian products simultaneously, integrating optics with electronics, and combining research, production and trade, our company will become a competitive optics and optoelectronic enterprise. We have passed the evaluations of ISO9001 and CE certifications.

An rangefinder is a instrument that you could use to measure the distance from a selected point or object. Adding ultrasonic to the mix, just adds an extra emphasis on sunlight. This easy to use sensor is from the Maxbotix company. The LV-MaxSonar-EZ1 offers very short to long-range detection and ranging, in an incredibly small package with ultra low power consumption. The LV-MaxSonar-EZ1 detects objects from 0-inches to 254-inches (6.45-meters) and provides sonar range information from 6-inches out to 254-inches with 1-inch resolution. Objects between 0-inches and 6-inches range as 6-inches. The interface output formats included are pulse width output, analog voltage output, and asynchronous serial digital output. People detection requires high sensitivity, yet a narrow beam angle requires low sensitivity. The LV-MaxSonar-EZ1 balances the detection of people with a narrow beam width. The EZ1 is the most popular MaxSonar Product. 42kHz Ultrasonic sensor. 20Hz reading rate. RS232 Serial Output - 9600bps (it's RS232 not TTL). Analog Output - 10mV/inch. PWM Output - 147uS/inch. Low 2mA supply current. 2.5-5.5V operation range. Small, light weight module.

Avoid obstacles and measure distances with the ultrasonic range finder. Device emits a high-frequency sound wave that alerts the robot to things in its path. A Programming Kit is needed to change the program in the Vex Controller. Expand functionality. Avoid obstacles. Measure distances. Create more autonomous function. Parallax's new PING))) ultrasonic sensor provides an inexpensive 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. -- 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 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 BASIC Stamp and Javelin Stamp microcontrollers is a snap.
