The LV-EZ4 from MaxBotix is a compact ultrasonic rangefinder that detects objects from 0 to 254 inches (6.45 metres), with calibrated range output from 6 to 254 inches at 1-inch resolution. Objects closer than 6 inches are reported as 6 inches. The EZ4 features the narrowest beam angle in the LV-MaxSonar-EZ series, making it well suited for applications that require reduced side-lobe sensitivity and tighter detection areas.
Three output formats are provided simultaneously: pulse width (PWM), analog voltage (Vcc/512 per inch), and RS232-compatible serial (9600 baud), giving you flexibility to interface with virtually any microcontroller or data acquisition system.
Key Features
- Range – 6 to 254 inches (15 cm to 6.45 m) with 1-inch resolution
- Narrowest Beam – Tightest beam pattern in the LV-MaxSonar-EZ family for reduced false triggers
- Three Output Modes – PWM, analog voltage, and serial (9600 baud) simultaneously
- Low Power – Operates from 2.5V to 5.5V
- Compact Form Factor – Small, lightweight package for easy integration
- Real-Time Ranging – Continuous distance readings for dynamic applications
Ideal For
- Robotics obstacle detection and navigation
- Proximity sensing in tight spaces
- Arduino and microcontroller distance measurement projects
- Applications requiring narrower beam width than standard ultrasonic sensors

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
