Hello everybody, I am Shafin, a member of Aiversity. I am going to share about how to build a water level sensor for water tanks with a Raspberry pi. This project is going to help you to understand the working of Raspberry pi in detail. if you want the video project, it is below.
Or, the written project is below
Now let’s talk about the connections of the raspberry pi, ultrasonic sensor and Buzzer.
Please follow the circuit diagram given below
Ultrasonic sensor vcc to 5v of Raspberry Pi
Ultrasonic sensor Gnd to Gnd of Raspberry Pi
Trigger to GPIO 2
Echo to GPIO 3
Buzzer + to GPIO 4
Buzzer – to Gnd
· Attach a scale to the bucket.
· Next attach the buzzer and ultrasonic sensor to the scale
Now you know the connections and the structure, let’s build the code.
1. Open the Thonny Python IDE
2. Download the Github code or from below:
3. Run the code.
