Ultrasonic Range Finder EZL1 (MB 1261)

Introduction

The MB1261 have a new high power output 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 MB1261 low power 3.3V to 5V operation provides very short to long-range detection and ranging, in a tiny and compact form factor. The MB1261 detect objects from 0-cm* to 1068-cm (35 feet) and provide sonar range information from 20-cm out to1068-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 are pulse width output (MB1261),  analog voltage output, and serial digital output.
