The distance measurement project is very helpful project which can be used in cars to avoid accidents or in any distance monitoring systems in industry and also can be used in liquid level indicators like fuel tanks in planes.
Connect ultrasonic sensor wireless.
Echo pin produces a pulse when the reflected signal is received.
The wireless transmitter circuit which is placed on the tank will send water level data every 5 seconds 24 7.
Trig trigger pin is used to trigger the ultrasonic sound pulses.
The transmitter consists of arduino nano ultrasonic sensor hc sr04 nrf24l01 module which will connect the transmitter and receiver wirelessly at 2 4 ghz.
The ultrasonic level sensor provides high accuracy ultrasonic proximity detection and ranging in air.
Wireless ultrasonic sensors the sure cross u gage k50u ultrasonic sensor works in a variety of environments to provide a measurement of the distance between the target and the sensor.
The radio bridge lora lorawan ultrasonic level sensors are designed for very long range and low cost applications.
Vcc is the power supply for hc sr04 ultrasonic distance sensor which we connect the 5v pin on the arduino.
It is designed to be used with a banner wireless node or multihop modbus radio creating a cost effective easy to use wireless solution for monitoring mobile.
The length of the pulse is proportional to the time it took for the transmitted signal to be detected.
Gnd should be connected to the ground of arduino.
