Several weeks ago, while facing problems getting my new gps to work, i decided to try something easier. The xlmaxsonarez sensors are not equipped with an internal temperature compensation. Our high performance ultrasonic range finders are made in america and shipped worldwide from our 22,000 square foot manufacturing facility in minnesota, usa. In addition, they may also report the range to larger size targets as closer than the actual distance. The sensor uses this stored information to range a close object. The xl maxsonar ez series has high power output along with realtime auto calibration for changing conditions temperature, voltage and acoustic or electrical noise that ensure you receive the most reliable in air ranging data for every reading taken.
The hrlvmaxsonarez sensor line correctly compensates for target size differences. For the maxsonar sensors you can start all the sensors at the same time by pulling the rx pins high for the 20us. The mbed is the brains on board my avc competition robot data bus. Tx delivers asynchronous serial with an rs232 format, except voltages are 05v. Sensor minimum distance the sensor minimum reported distance is 6inches 1 5. The lv maxsonar ez1 is the or iginal maxsona r product. Features of the mb1040, lvmaxsonarez4, include oneinch resolution, the narrowest beam width of any sensor in the lv. They answered all the questions that i had regarding the sensor and the information on the datasheet. However, the lvmaxsonarez will range and report targets to the front sensor face. Recommended current capability of 3ma for 5v, and 2ma for 3v. In general, the lvmaxsonarez will report the rang e to the leading edge of the closest detectable obj ect. Users can measure how far away an object is with an accuracy within 1 inch to over 20 feet away. This is our m ost popular indoo r ultrasonic sensor and is a.
This pin outputs a pulse width representation of the distance with a scale factor of 1us per mm.
