HC-SR04 HC SR04 Arduino Ultrasonic Sensor

About this item
  • [Ultrasonic Distance Sensor]: HC-SR04 Spec. Power Supply: 3.5-5V DC; Quiescent Current : <2mA; Effectual Angle: <15°
  • [Sensor Detection Range]: Front distance 5V: 0.78~17.72 in/ (2cm~450cm); 3.3V: 0.78~15.75in/(2cm~400cm) ; High precision: up to 0.12 in/(0.3 cm) Effectual angle: less than 15°
  • [HC-SR04P Module]: Operating with IO trigger for at least 10us high-level signal, when triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object, the duration of the signal is the time from sending ultrasonic to returning
  • [Easy to Install and Apply]: Winscon distance sensor is a 4PIN with VCC; Trig(Control Side); Echo (Receiver); Out (Empty); GND; Small Size Designed, provide an easy for embedded installation in widely used for Robot Obstacle Avoidance, Object Distance Measuring, Liquid Level Detection, Public Security, Parking Lot Detection, etc.
  • [Module Ranging Principle]: The distance between the unit and the object is calculated by measuring the traveling time of sound and outputting it as the width of a TTL pulse, which is calculated by L = 1/2 × T × C (L is the distance, T is the time between the emission and reception, and C is the sonic speed).

Product Description

 

Winscon Ultrasonic Distance Sensor Feature :

HC-SR04R Ultrasonic Sensor

Power Supply:3.3-5V DC

Quiescent Current : <2mA

Effectual Angle: <15°

Ranging Distance : 3.3V: 0.78~15.75in/(2cm~400cm); 5V: 0.78~17.72 in/ (2cm~450cm)

Resolution : 0.12 in/(0.3 cm)

Output Signal: Electric frequency signal, high-level 5V, low-level 0V

 

Module Working Principle:

  • Pull the Trig Pin to a 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.
  • The distance between the unit and the object is calculated by measuring the traveling time of sound and outputting it as the width of a TTL pulse, which is calculated by L = 1/2 × T × C (L is the distance, T is the time between the emission and reception, and C is the sonic speed).
  • The Distance = (Duration of High Level*Sonic: 340m/s) /2.

 

Important Operation Note:

1. Before Powered, HC-SR04R Sensor Module Should be Inserted in the Circuit to Avoid Producing High Level of Misoperate ; if Misoperate, Power the Module Again.

2. HC-SR04 Ultrasonic Distance Sensor is NOT Suggested to Connect to Electric Directly, When Connected to Electric, the GND Terminal Should be Connected w/ Sensor Module, Otherwise, it will affect the Module’s Normal Work.

3. When Tested Objects, the Area Range Should be More than 0.5 Square Meters and the Plane Requests Smoothly; Otherwise, it will Affect the Results of Measuring.
