ultrasonic level sensor

The ultrasonic sensor emits a high-frequency sound pulse and calculates the distance depending upon the time taken by the echo signal to travel back after reflecting from the desired target. The width of pulse or on-time of the pulse depends on the distance between the ultrasonic sensor and the obstacle which is placed in front of the HC-SR04 sensor.

Further details on ultrasonic sensor working are provided in the next section.

. Ultrasonic Sensor HC-SR04 Connections. Ultrasonic Sensor for Measuring Water Level. How the ultrasonic sensor work.

VCC and GND go to 5V and GND pins on the Arduino and the Trig and Echo go to any digital Arduino pinUsing the Trig pin we send the ultrasound wave from the transmitter and with the Echo pin we listen for the reflected signal. So now as we know the working of the ultrasonic sensor it is pretty straightforward to understand the working of the project. The non-contact liquid level sensor features our proprietary Reflective Technology that delivers reliable level measurement in condensing.

How the HC-SR04 Ultrasonic Distance Sensor Works. The sensor has 4 pins. After the distance is calculated it will.

The speed of sound is 341 meters per second in air. Considering the travel time and the speed of the sound you can calculate the distance. It emits an ultrasound at 40 000 Hz which travels through the air and.

The HC-SR04 Ultrasonic Module has 4 pins Ground VCC Trig and Echo. We just have to read the values from the sensor and convert it to CMs and after doing all that we have to publish the data in a local webserver that will be created by our. The echo pin produces a pulse as an output.

It emits an ultrasound at 40 000 Hz which travels through the air and if there is an object or obstacle on its path It will bounce back to the module. The Ground and the VCC pins of the module needs to be connected to the Ground and the 5 volts pins on the Arduino Board respectively and the trig and echo pins to any Digital IO pin on the Arduino Board. The general purpose reflective ultrasonic multi-function level transmitter provides continuous level measurement up to 98 3m with a 4-20 mA analog signal output and four relays and is configured via our WebCal software.

Next level ultrasonic sensor. In idle conditions this pin remains at an active low level.
