Ultrasonic Sensor Diagram. The ultrasonic sensor has four terminals 5v trigger echo and gnd connected as follows connect the 5v pin to 5v on your arduino board. The us sensor can be powered by 5v and hence it is directly powered by the 7805 voltage regulator.
As shown above the hc sr04 ultrasonic us sensor is a 4 pin module whose pin names are vcc trigger echo and ground respectively. As shown above the hc sr04 ultrasonic us sensor is a 4 pin module whose pin names are vcc trigger echo and ground respectively. The ultrasonic sensor sends the ultrasonic pulse at 40 khz which travels through the air.
Figure 2 circuit diagram of ultrasonic senor the ultrasonic sensor circuit consists of set of ultrasonic transmitter and receiver which are operated at same frequency.
As shown above the hc sr04 ultrasonic us sensor is a 4 pin module whose pin names are vcc trigger echo and ground respectively. As shown the circuit involves nothing more than a lcd display and the ultrasonic sensor itself.
