The ph of pure water is 7.
Arduino water meter reader.
So it can be so helpful to hang a picture.
In general water with a ph lower than 7 is considered acidic and with a ph greater than 7 is considered basic.
It emits an infrared light and detects the reflection.
This a project i ve been working for some time now.
Arduino hall effect water flow meter.
A project log for fly wars.
So i built my smart meter model mm 93 based on arduino with some awesome features hope you like and enjoy the project.
The normal range for ph in surface water systems is 6 5 to 8 5 and the ph range for groundwater systems is between 6 to 8 5.
However if you have an older power meter without a pulse output then you might be able to use one of the options below to sense your water consumption.
The idea is to make a sensor which can sense the water levelin tanks where the motor pumps are used.
The code is shown in the attached images here is the link to download the energy meter code.
The solution was a 15 meter length of four conductor.
This videos explain a lot of details about the project fabrications.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
It is a device that shows in a little lcd display the distance to the nearest object it can find usually the floor the ceilling and two walls or columns.
There was also the issue of how to power the arduino and magnetometer i had placed at the water meter which is well separated from my house.
The project under discussion has the capability to checkthe water level and also send the data over wifi.
Using technology and a hackers mindset to increase food security for the coming billions last updated 21 9 2015.
Connect arduino with the laptop and open the serial monitor.
Use the tcrt5000 ir barrier line track sensor.
And it worked well.
Least 4 minutes you find the testing experiment on mm 93.
To check the water level ultrasonic hc sr04 is the distancesensor.
So the water under.
Because your setup ct resistors and input voltage may be different there is a scaling factor in the sketch which you will need to change before you will get.
