Design with us-016 ultrasonic in Cirkit DesignerThe US-016 ultrasonic sensor, manufactured by Arduino (Part ID: US-016), is a highly reliable and accurate distance measuring device. It operates by emitting ultrasonic sound waves and calculating the time it takes for the echo to return after hitting an object. This time measurement is then used to determine the distance to the object based on the speed of sound.
This circuit is a distance measurement and communication system using an Arduino UNO, an ultrasonic sensor, an OLED display, and a SIM900A module. The ultrasonic sensor measures the distance to an object, which is then displayed on the OLED screen and transmitted via the SIM900A module. The system is powered by a 18650 Li-ion battery.

This circuit features an Arduino Mega 2560 microcontroller interfaced with multiple HC-SR04 ultrasonic sensors and two HC-06 Bluetooth modules. The ultrasonic sensors are likely used for distance measurement or object detection, while the Bluetooth modules enable wireless communication. Additionally, there is an I2C LCD display for outputting information such as sensor readings or system status.

This circuit is designed to function as an ultrasonic radar system, utilizing an Arduino UNO microcontroller, an HC-SR04 ultrasonic sensor, and an SG90 servo motor. The Arduino controls the servo to sweep the ultrasonic sensor through a range of angles, while the sensor measures the distance to any objects in its path. The system outputs the angle and distance measurements to the serial monitor and provides an indication when an obstacle is detected within 20 cm.

The US-016 sensor has four pins, as described in the table below:
| Pin | Name | Description |
|---|---|---|
| 1 | VCC | Power supply pin. Connect to 5V DC. |
| 2 | Trig | Trigger pin. Send a 10 µs TTL pulse to initiate distance measurement. |
| 3 | Echo | Echo pin. Outputs a PWM signal proportional to the measured distance. |
| 4 | GND | Ground pin. Connect to the ground of the power supply. |
Below is an example of how to use the US-016 ultrasonic sensor with an Arduino UNO:
// Define pin connections
const int trigPin = 9; // Trigger pin connected to digital pin 9
const int echoPin = 10; // Echo pin connected to digital pin 10
void setup() {
pinMode(trigPin, OUTPUT); // Set the trigger pin as an output
pinMode(echoPin, INPUT); // Set the echo pin as an input
Serial.begin(9600); // Initialize serial communication at 9600 baud
}
void loop() {
// Send a 10 µs pulse to the trigger pin
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
// Measure the duration of the echo pulse
long duration = pulseIn(echoPin, HIGH);
// Calculate the distance in cm
float distance = (duration * 0.0343) / 2;
// Print the distance to the Serial Monitor
Serial.print("Distance: ");
Serial.print(distance);
Serial.println(" cm");
delay(500); // Wait for 500 ms before the next measurement
}

Q: Can the US-016 measure distances through transparent materials like glass?
A: No, the US-016 ultrasonic sensor cannot measure distances through transparent materials, as ultrasonic waves do not pass through them effectively.
Q: What is the maximum angle of detection for the US-016?
A: The US-016 has a detection angle of approximately 15 degrees. Ensure objects are within this angle for accurate measurements.
Q: Can I use the US-016 with a 3.3V microcontroller?
A: The US-016 requires a 5V power supply for proper operation. If using a 3.3V microcontroller, a level shifter is recommended for the Trig and Echo pins.
