Ultrasonic Range Finder MB1040 EZ4

Introduction

EZ4 (EZ Series) is an indoor, compact, low cost easy to use ultrasonic range sensor with narrowest beam width than all EZx Series Ultrasonic sensor from MaxBotix. EZ4 is the narrowest beam width sensor that is the least sensitive to side objects and it is an excellent choice when only larger objects need to be detected. It gives range output in terms of analog voltage, serial data and PWM signals. You can cascade many of these sensors together to take distance reading of the surrounding area without any interference from the adjacent sensor.
To select correct sensor for your application refer to Sensor Selection Guide.
With 2.5V - 5.5V power the EZ4 provides very short to long-range detection and ranging, in an incredibly small package. It detects objects from 15cm to 645 cm (6 inches to 254 inches) with the resolution of 2.5cm (1 inch). Objects closer than 6 inches range as 6 inches. It gives range output in the Analog, Pulse Width Modulation (PWM) and in the serial format which makes it very convenient for interfacing. EZ0 to EZ4 sensors have progressively narrower beam width. Select sensor according to your application.
