This instructable video is all about how to monitor the Quality of water, interns of monitoring the level of water, the temperature of the water and its surrounding, the turbidity of the water (how clean the water is) as well as the PH levels of the Water. So this system monitors all of these aspect and finally when all check have been completed, its sends the information or data as an SMS to notify the authorized personnel.
Step 1: Components Needed1 / 7
For you to be able to complete this project you need to get these specific kind of devices.
1. Arduino Mega Board.
2. (16 * 2) LCD display.
3. The 2 in one Temperature and PH sensor.
4. The Turrbidity Sensor.
5. A GSM shield.
6. An ultrasonic Sensor.
7. 4 RGB led.
8. A buzzer.
Step 2: Graphical View and Circuit Diagram1 / 2
Attached are the circuit diagram and the Fritzing view of the project.
Step 3: The Arduino Code and Library UsedAttached are the whole code for the Project and the library used to run the Code.
