## Description

The MB1040 LV-MaxSonar-EZ4 is a compact ultrasonic range sensor from MaxBotix that provides distance measurements from 15 cm to 645 cm (6" to 254") with 2.5 cm (1") resolution. It features the narrowest beam width of any sensor in the LV-MaxSonar-EZ line, making it best suited for detecting larger objects. The sensor outputs range data in three formats — analogue voltage, RS232 serial, and pulse width — at a 20 Hz read rate. It operates on 2.5–5.5 V with a low 2.0 mA average current draw, and includes mounting holes for easy installation. Key Features Narrowest Beam Width – Most focused beam in the LV-MaxSonar-EZ sensor line 15–645 cm Range – Objects closer than 15 cm (6") report as 15 cm 2.5 cm (1") Resolution – At a 20 Hz reading rate Three Output Modes – Analogue voltage, RS232 serial, and pulse width 42 kHz Ultrasonic Sensor – Reliable distance measurement Low Power – 2.0 mA average current, 2.5–5.5 V operating voltage Auto-Calibration – Learns ringdown pattern at power-up to adapt to the environment Compact & Lightweight – Less than 16 cm³ (1 in³) with built-in mounting holes RoHS Compliant Ideal For Large object detection applications Robotics and obstacle avoidance Proximity sensing and level measurement Package Contents 1× MB1040 LV-MaxSonar-EZ4 ultrasonic sensor Resources LV-MaxSonar-EZ4 Datasheet
