Learn how to use HC-SR04 Ultrasonic Sensor with the ESP32 board using the Arduino core. The ultrasonic sensor uses sonar to determine the distance to an object.
The ultrasonic sensor works on the principle of SONAR and RADAR system which is used to determine the distance to an object. An ultrasonic sensor generates high-frequency sound (ultrasound) waves. When this ultrasound hits the object, it reflects as echo which is sensed by the receiver as show...

unlike most ultrasonic rangefinders which need 5V to work well. To allow it to survive the elements of an all-weather application like this, I soldered the connecting wires and encased the circuit board in 5-minute epoxy. Pictured is my tank's vent cap with the sensor held in place with...
