HC-SR04 Ultrasonic Sensor Distance Module, for All Type of Development Board Electronic school science Projects (Ultrasonic Sensor Best Quality Product)

Name : HC-SR04 Ultrasonic Sensor Distance Module, for All Type of Development Board Electronic school science Projects (Ultrasonic Sensor Best Quality Product)

Color : Aqua Blue

SPECIFICATION : - .Power Supply: DC 5V .Quiescent Current : <2mA .Effectual Angle: <15° .Ranging Distance: 2 - 500cm .Trigger Input Pulse Width: 10uS .Resolution : 0.3cm .Dimensions: 1.3 x 0.4 x 0.1in / 3.03 x 1 x 0.25cm (L*W*H) .Connection: VCC/ Trig(T)/ Echo(R)/ GND (VCC: 5V; GND is Ground Wire; TRIG is Trigger Control Signal Input;, ECHO is Echo Signal Output.) HC-SR04 WORK WITH ARDUINO PROJECT:- .HC-SR04 Compatible with Arduino Ultrasonic Sensor Can Send Eight 40 kHz and Detect Signal Back. .When Signal Back, a High Level Signal Will be Outputed by IO, and the Duration of the Signal is the Time from Sending Ultrasonic to Returning. ULTRASONIC TIMING DIAGRAM:- Trigger Signal-10uS TTL Module Transmit Signal-40KHz Output Echo Signal MODULE WORKING PRINCIPLE:- .Pull the Trig Pin to High Level for More Than 10us Impulse and the Module Start Ranging. .The Module Sends Eight 40KHz Square Wave to Detect Whether a Signal is Returned Automatically. .Finished Ranging, If Find an Object in the Front, Echo Pin will be High Level; Different Distance, Different Duration of High Level. .So It is Easy to Calculate the Distance; The Distance = (Duration of High Level*Sonic: 340m/s) /2. PAY ATTENTION:- .1. Before Powered,HC-SR04 Sensor Module Should be Inserted in the Circuit to Avoid Producing High Level of Misoperate; if Misoperated ,Power the Module Again. .2.
