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](https://core-electronics.com.au/maxbotix-xl-maxsonar-ez0-sonar-range-finder-mb1200.html) and [XL-MaxSonar-AE](https://core-electronics.com.au/maxbotix-xl-maxsonar-ae0-sonar-range-finder-mb1300.html) families of distance sensors. **Specifications and Features** - Small and light: 0.870" x 0.785" x 0.645" (2.2 x 2.0 x 1.6 cm), 0.15 oz (4.3 g) - Long range detection: 0 – 6.45 m (21.2 ft) - No dead zone (detections from 0 to 6" are output as 6") - Resolution of 1" (2.5 cm) - Low typical current consumption: 2 mA - Runs on 2.5 – 5.5 V - 42 kHz ultrasonic sensor - 20 Hz reading rate - Free-run or triggered operation - Three interfaces (all are active simultaneously): - Serial output: asynchronous, logic-level, inverted, 9600 bps 8N1 - Analog output: (Vcc/512) / inch (10 mV/inch when input voltage Vcc = 5 V) - Pulse width output: 147 µs/inch **Selecting the right distance sensor** Since there are 15 members of the XL- and LV-MaxSonar acoustic distance sensor family, Pololu recommend using the [Maxbotix sonar range finder selection guide](https://www.maxbotix.com/SelectionGuide/Selection-Guide.htm) when choosing a acoustic range sensor for your application. There are 5 different beam configurations for the LV-MaxSonar family (EZ0 – EZ4), each pictured below. | [![](https://a.pololu-files.com/picture/0J442.400.jpg?1121c9bcf29f15775a41599b6bd59478)](https://a.pololu-files.com/picture/0J442.1200.jpg?1121c9bcf29f15775a41599b6bd59478) | |---| | LV-MaxSonar-EZ beam patterns (range shown on 1-foot grid to various diameter dowels) | [Maxbotix LV-MaxSonar-EZ0 MB1000](https://core-electronics.com.au/maxbotix-lv-maxsonar-ez0-sonar-range-finder-mb1000.html) beam characteristics: | [![](https://a.pololu-files.com/picture/0J440.400.jpg?eb4b0cd0c1c7c97be4538476858063fd)](https://a.pololu-files.com/picture/0J440.1200.jpg?eb4b0cd0c1c7c97be4538476858063fd) | |---| [Maxbotix LV-MaxSonar-EZ1 MB1010](https://core-electronics.com.au/maxbotix-lv-maxsonar-ez1-sonar-range-finder-mb1010.html) beam characteristics: | [![](https://a.pololu-files.com/picture/0J441.400.jpg?6896eb24a8dadc3db8cca51a69290d84)](https://a.pololu-files.com/picture/0J441.1200.jpg?6896eb24a8dadc3db8cca51a69290d84) | |---| [Maxbotix LV-MaxSonar-EZ2 MB1020](https://core-electronics.com.au/maxbotix-lv-maxsonar-ez2-sonar-range-finder-mb1020.html) beam characteristics: | [![](https://a.pololu-files.com/picture/0J1077.400.jpg?90339a19a11037413e93c333b2f1b45d)](https://a.pololu-files.com/picture/0J1077.1200.jpg?90339a19a11037413e93c333b2f1b45d) | |---| [Maxbotix LV-MaxSonar-EZ3 MB1030](https://core-electronics.com.au/maxbotix-lv-maxsonar-ez3-sonar-range-finder-mb1030.html) beam characteristics: | [![](https://a.pololu-files.com/picture/0J1078.400.jpg?9e09df908c5757e5700f1312238e66a2)](https://a.pololu-files.com/picture/0J1078.1200.jpg?9e09df908c5757e5700f1312238e66a2) | |---| [Maxbotix LV-MaxSonar-EZ4 MB1040](https://core-electronics.com.au/maxbotix-lv-maxsonar-ez4-sonar-range-finder-mb1040.html) beam characteristics: | [![](https://a.pololu-files.com/picture/0J1079.400.jpg?186aabbeb813cf85029b615d5b9d1c1b)](https://a.pololu-files.com/picture/0J1079.1200.jpg?186aabbeb813cf85029b615d5b9d1c1b) | |---| **People often buy this product together with:** | [![Sharp GP2Y0A21YK0F Analog Distance Sensor 10-80cm](https://a.pololu-files.com/picture/0J149.100.jpg?1072490e4e4bbd08443c814c561dcf2c)](https://core-electronics.com.au/sharp-gp2y0a21yk0f-analog-distance-sensor-10-80cm.html) | [Sharp GP2Y0A21YK0F Analog Distance Sensor 10-80cm](https://core-electronics.com.au/sharp-gp2y0a21yk0f-analog-distance-sensor-10-80cm.html) | |---|---| | [![Pololu Universal Aluminum Mounting Hub for 4mm Shaft, #4-40 Holes (2-Pack)](https://a.pololu-files.com/picture/0J1106.100.jpg?46a23ff3e5be0d235783ab6d78a37749)](https://core-electronics.com.au/pololu-universal-aluminum-mounting-hub-for-4mm-shaft-4-40-holes-2-pack.html) | [Pololu Universal Aluminum Mounting Hub for 4mm Shaft, #4-40 Holes (2-Pack)](https://core-electronics.com.au/pololu-universal-aluminum-mounting-hub-for-4mm-shaft-4-40-holes-2-pack.html) | |---|---| | [![Sharp GP2Y0A02YK0F Analog Distance Sensor 20-150cm](https://a.pololu-files.com/picture/0J1125.100.jpg?41bbea967aee78df7329bc0a1261b970)](https://core-electronics.com.au/sharp-gp2y0a02yk0f-analog-distance-sensor-20-150cm.html) | [Sharp GP2Y0A02YK0F Analog Distance Sensor 20-150cm](https://core-electronics.com.au/sharp-gp2y0a02yk0f-analog-distance-sensor-20-150cm.html) | |---|---| **Dimensions** | Size: | 0.870" x 0.786" x 0.645" | |---|---| | Weight: | 4.3 g | **General specifications** | Resolution: | 2.5 cm | |---|---| | Maximum range: | 6.45 m | | Minimum range: | 0 m[1](https://core-electronics.com.au/#note1) | | Sampling rate: | 20 Hz | | Baud: | 9600 | | Minimum operating voltage: | 2.5 V | | Maximum operating voltage: | 5.5 V | | Supply current: | 2 mA | **Notes:** 1Objects closer than 15 in are reported as 15 in. **File downloads** - **LV-MaxSonar-EZ beam width comparison (224k pdf)** **Recommended links** - **[Maxbotix sonar range finder selection guide](https://www.maxbotix.com/SelectionGuide/Selection-Guide.htm)** - **[Report on Maxbotix sonar range finder tests](https://maxbotix.com/documents/MaxSonar_Reliability_Demonstration_Test__RDT__and_MTBF_Report.pdf)** This report explains testing procedures, calculations, and conclusions for Maxbotix’s reliability demonstration test and mean time between failure (MTBF) test.
