5pcs US-026 Ultrasonic Module Distance Sensor Kits Ranging Module for Servo Arduino

Parameter:Working voltage: DC 3V-5.5VWorking current: 5.3mAWorking temperature: -40℃-85℃Output mode: GPIOInduction degree: Less than 15 degreeRanging range: 2cm-600cmRanging accuracy: 0.1cm+1%Dimension: 45*20*1.2 mm4 pin interface definition:1st pin: access power VCC(direct current 3V-5.5V )2nd pin: access the Trig port of outside circuit, ranging will be triggered by input a 10uS above high level to this pin.3rd pin: access the Echo port of the outside circuit, after finishing ranging, the pin will output a high level, the width of the high level equal round trip time of ultrasonic.4th pin: access ground of outside circuit.Measuring Period and Range Exceeding:While the distance exceeds the measuring range of US-026, the high level signal will output through Echo pin still, and the width is 66ms.Measuring period: After exporting a high electrical level impulse by ECHO pin, the next measurement can be taken. So the measuring period is decided by the distance, shorter distance means narr
