Introduction: Water Level Monitor With Raspberry Pi
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.
Step 1: Connections
Now let’s talk about the connections of the raspberry pi, ultrasonic sensor and Buzzer.Please follow the circuit diagram as given
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
Step 2: Structure
· Attach a scale to the bucket.
· Next attach the buzzer and ultrasonic sensor to the scale
Step 3: Code
Now you know the connections and the structure, let’s build the code.
1. Open the Thonny Python IDE
2. Download the Github code: -- https://github.com/Aiversity/Raspberry-pi-project..
3. Open and run the code.
Step 4: Testing
Fill water in the bucket. When the distance of ultrasonic sensor from the water is around 4 centimetre, the buzzer will beep, alerting the bucket is almost full.
