Ultrasonic sensor wiring diagram. In this session well look at the basic sensor wiring for both six wire and nine wire sensors. The hc sr04 ultrasonic sensor uses sonar to determine distance to an object like bats do. As shown above the hc sr04 ultrasonic us sensor is a 4 pin module whose pin names are vcc trigger echo and ground respectively. Hc sr04 ultrasonic sensor working. You can place the ultrasonic sensor as shown on the breadboard and with jumper wires complete the wiring to the arduino. The electrical wiring diagram for an actual ultrasonic sensor to an arduino.
If you are using a 4 pin ultrasonic sensor the normally closed pin nc is wired to ground. These transducers are better than the infrared sensors because these ultrasonic transducersensors are not affected by the smoke black materials etc. It offers excellent non contact range detection with high accuracy and stable readings in an easy to use package. Well click on the workspace icon on the toolbar and im going to load the default settings for a tspc 30s1 toughsonic 14 sensor. Ultrasonic sensors exhibit excellence in suppressing background interference. This sensor is a very popular sensor used in many applications where measuring distance or sensing objects are required.
As you can see the illustration below the sensor trigger pin is connected to d1 which is pin 5 in arduino board and the echo is connected to d2 which is pin 4 in arduino board. Youll notice on the toolbar several of the icons are in color and. Were here in the main workspace window. We provide a schematic diagram on how to wire the ultrasonic sensor and an example sketch to use with the arduino.
