## Description

Basic information of the module : 1: Working voltage: DC5V 2: Quiescent current: less than 2mA 3: Level output: High 5V 4: Level output: Bottom 0V 5: Sensing angle: no more than 15 degrees 6: Detection range: 2-450cm 7: High precision: up to 0.3cm How the module works: (1)Using IO trigger ranging, sending at least 10us of high level signal; (2)the module automatically sends eight 40khz square wave, automatically detect whether there is signal returning; (3)If there is a signal returning, Output a high level through IO, The lasting time of the High level is the time from the launch to the return of ultrasound. Test distance = (high level lasting time * velocity of sound (340M / S)) / 2 What is in the package: 2* Ultrasonic Wave Sensor
