ESP32 Interfacing With Ultrasonic Sensor

In This Blog I Will Just Interfacing The Ultrasonic Sensor With Esp32 Board .In Serial Monitor The Will Display The Output Of Ultrasonic Sensor In The Form Of CM.

This Will Block Diagram -

Circuit Diagram :-

Just Interfacing The Ultrasonic Sensor With Esp32 In BradBoard -

When You Put The Hand Of Near Of Ultrasonic Sensor 

Image Will Show The Code Of This Project 

Serial Monitor Show The Out Of Ultrasonic Sensor

Code :-

//Prateek //www.prateks.in //https://www.youtube.com/c/JustDoElectronics #define TRIG_PIN 33 // ESP32 pin GIOP33 connected to Ultrasonic Sensor's TRIG pin #define ECHO_PIN 22 // ESP32 pin GIOP22 connected to Ultrasonic Sensor's ECHO pin float duration_us, distance_cm; void setup() { // begin serial port Serial.begin (9600); // configure the trigger pin to output mode pinMode(TRIG_PIN, OUTPUT); // configure the echo pin to input mode pinMode(ECHO_PIN, INPUT); } void loop() { // generate 10-microsecond pulse to TRIG pin digitalWrite(TRIG_PIN, HIGH); delayMicroseconds(10); digitalWrite(TRIG_PIN, LOW); // measure duration of pulse from ECHO pin duration_us = pulseIn(ECHO_PIN, HIGH); // calculate the distance distance_cm = 0.017 * duration_us; // print the value to Serial Monitor Serial.print("distance: "); Serial.print(distance_cm); Serial.println(" cm"); delay(500); }
