Wireless Ultrasonic Sensor Arduino

Hello again as i promised i uploaded my next instructable.

Wireless ultrasonic sensor arduino.

Echo pin produces a pulse when the reflected signal is received. It controlled with a free app via bluetooth. It uses an ultrasonic distance sensor and a buzzer. Wireless water level indicator using ultrasonic sensor arduino is an amazing and very useful project.

The wireless transmitter circuit which is placed on the tank will send water level data every 5 seconds 24 7. Water level indicator using arduino. It offers excellent non contact range detection with high. 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. And the distance after. The objective of this project is to notify the user the amount of water that is present in the overhead water tank. Arduino ultrasonic sensor the hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do.

To make it. Gnd should be connected to the ground of arduino. This one is going to cover bluetooth and ultrasonic sensor hc sr04 why those two. 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 serial monitor is used for receive or send data to the arduino card. I don t find ultrasonic sensor in fritzing for the schematics so i will say the connections here. This project can be made wireless for better looks. I do not have a circuit schematic maker so here is the circuit.

Vcc goes to 5v on arduino. The length of the pulse is proportional to the time it took for the transmitted signal to be detected. This window can t be clear so you must close it to clear what you write. Vcc is the power supply for hc sr04 ultrasonic distance sensor which we connect the 5v pin on the arduino.

So the program will print on the monitor distance in cm. Trig trigger pin is used to trigger the ultrasonic sound pulses. Just put your hand in front of the sensor and you will hear the buzzer from the inside. Gnd goes to ground pin on arduino.
