Maxbotix mb1040 lvmaxsonarez4 ultrasonic sensor sonar. We have been driving innovation in the ultrasonic sensor industry since our inception. In general, the lvmaxsonarez will report the rang e to the leading edge of the closest detectable obj ect. The maxsonarez1 detects objects from 0inches to 254inches 6. Under freerun operation, range readings can be taken every 50.
If temperature compensation is desired, contact maxbotix and request the temperature compensation formula pdf. Maxsonar ez1 timing is factory calibrated to one percent at five volts, and in use is better than two percent. 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. Our high performance ultrasonic range finders are made in america and shipped worldwide from our 22,000 square foot manufacturing facility in minnesota, usa.

Maxsonarez1 data sheet the maxsonarez1 high performance sonar range finder the maxsonarez1 offers very short to longrange detection and ranging, in an incredibly small package with ultra low power consumption. However, the lvmaxsonarez will range and report targets to the front sensor face. Hrusb maxsonar ez is equipped with an internal temperature sensor which allows the sensor to apply a compensation for speed of sound changes. The lv maxsonar ez1 is the or iginal maxsona r product. Hrusbmaxsonarez is equipped with an internal temperature sensor which allows the sensor to apply a compensation for speed of sound changes. Tx delivers asynchronous serial with an rs232 format, except voltages are 05v. I2cxlmaxsonar ez series high performance sonar range finder mb1202, mb1212, mb1222, mb1232, mb1242 the i2cxlmaxsonarez series is the first maxsonar ultrasonic sensor to feature the i2c interface. Mcu of choice for the interfacing project was the arm cortex m3based mbed. Maxbotixs lvmaxsonarez series are low power, high performance sonar range finders. The xlmaxsonarez sensors are not equipped with an internal temperature compensation. Features of the mb1040, lvmaxsonarez4, include oneinch resolution, the narrowest beam width of any sensor in the lv.
Ez1 is a great choice for use where sensitivity is needed along with side object rejection. The maxsonarez4 detects objects from 0inches to 254inches 6. The mbed is the brains on board my avc competition robot data bus. Users can measure how far away an object is with an accuracy within 1 inch to over 20 feet away. The hrlvmaxsonarez sensor line provides high accuracy and high resolution ultrasonic.
