Ultrasonic Range Finder XL-EZ4 (MB 1240)

Introduction

EZ4 Ultrasonic Range Finder is a high power sensor with noise from the Maxbotics. EZ4 (MB1240) have a new high power output transducer along with real-time auto calibration for changing conditions (temperature, voltage or acoustic or electrical noise) that ensure you receive the most reliable (in air) ranging data for every reading taken. The MB1240 consumes very low power at 3.3V – 5V operation provides very short to long-range detection and ranging, in a tiny and compact form factor. The MB1240 detect objects from 0-cm* to 645cm (25.1 feet) and provide sonar range information from 20-cm out to 765-cm with 1-cm resolution. Objects from 0-cm* to 20-cm typically range as 20-cm. (*objects from 0-mm to 1-mm may not be detected). The interface output formats included PWM, analog voltage output, and serial digital output.
