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.
Trig trigger pin is used to trigger the ultrasonic sound pulses.
The radio bridge lora lorawan ultrasonic level sensors are designed for very long range and low cost applications.
The length of the pulse is proportional to the time it took for the transmitted signal to be detected.
Vcc is the power supply for hc sr04 ultrasonic distance sensor which we connect the 5v pin on the arduino.
Gnd should be connected to the ground of arduino.
It offers excellent non contact range detection with high accuracy and stable readings in an easy to use package from 2 cm to 400 cm or 1 to 13 feet.
Echo pin produces a pulse when the reflected signal is received.
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 transmitter consists of arduino nano ultrasonic sensor hc sr04 nrf24l01 module which will connect the transmitter and receiver wirelessly at 2 4 ghz.
Wireless distance measurement using ultrasonic sensor introduction.
The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do.
The ultrasonic level sensor provides high accuracy ultrasonic proximity detection and ranging in air.
