This compact sonar range finder by Maxbotix detects objects from 0 to 6.45 m (21.2 ft) with a resolution of 2.5 cm (1") for distances beyond 15 cm (6"). Unlike other sonar range finders, the LV-MaxSonar has virtually no dead zone: it can detect even small objects up to and touching the front sensor face!The EZ0, EZ1, EZ2, EZ3, and EZ4 versions have progressively narrower beam angles.

The Maxbotix LV-MaxSonar-EZ family of sonar range finders offers very short- to long-range detection and ranging in an incredibly small package with ultra-low power consumption. The LV-MaxSonar-EZ detects objects from 0 to 6.45 meters (21.2 feet) and provides sonar range information beyond 15 cm (6") with a resolution of 2.5 cm resolution (1 in). Objects between 0 and 15 cm range as 15 cm. The sensor provides three output interfaces, all of which are active simultaneously: digital pulse width output, analog voltage output, and asynchronous serial digital output. The LV-MaxSonar is available in five factory-calibrated beam patterns (EZ0-4).

For a higher-resolution, longer-range version, please consider the XL-MaxSonar-EZ and XL-MaxSonar-AE families of distance sensors.

The HRLV-MaxSonar-EZ sensor line is the most cost-effective solution for applications where precision range-finding, low-voltage operation, space saving, and low-cost are needed.

The HRLV-MaxSonar-EZ sensor line provides high accuracy and high resolution ultrasonic proximity detection and ranging in air, in a package less than one cubic inch. This sensor line features 1mm resolution, target-size and operating-voltage compensation for improved accuracy, superior rejection of outside noise sources, internal speed-of-sound temperature compensation and optional external speed-of-sound temperature compensation. This ultrasonic sensor detects objects from 1mm to 5meters, senses range to objects from 30cm to 5meters, with large objects closer than 30cm typically reported as 30cm. The interface output formats are pulse width, analog voltage, and serial digital in either RS232 or TTL. Factory calibration is standard.

A good sensor for when a Sharp IR distance sensor won't cut it. For example of using this with an Arduino, see the Halloween Pumpkin project.

HRLV-EZ0 Data Sheet / Product Information Guide is available here. By default this sensor outputs RS-232 logic level data, to use it in TTL logic mode, solder closed the square jumper on the back.

The different HRLV models have different beam width patterns, check this image for a comparison of all the HRLV model beam patterns. If you don't need high sensitivity, or want a longer range, check out the LV models - They are meant for up to 6.5 meter distances

LV-EZ4 Maxbotix Ultrasonic Rangefinder provides very short to long-range detection and ranging, in an incredibly small package. It can detect 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 from 0 inches to 6-inches range as 6-inches.) The interface output formats included are pulse width output (PWM), analog voltage output (Vcc/512 volts per inch), and serial digital output (9600 baud).

Many applications require a narrower beam or lower sensitivity than the LV MaxSonar EZ1. Consequently, MaxBotix is offering the EZ2, EZ3, & EZ4 with progressively narrower beam angles allowing the sensor to match the application.
