The ph of pure water is 7.
Arduino water meter reader.
In this project we will interface yfs201 hall effect water flow sensor with arduino for measuring flow rate and volume of water or any other liquid.
This a project i ve been working for some time now.
In general water with a ph lower than 7 is considered acidic and with a ph greater than 7 is considered basic.
The solution was a 15 meter length of four conductor.
In some cases newer water meters are equipped with a pulse output.
A hackers solution to world hunger.
So it can be so helpful to hang a picture.
The idea is to make a sensor which can sense the water levelin tanks where the motor pumps are used.
The project under discussion has the capability to checkthe water level and also send the data over wifi.
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.
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.
Connect arduino with the laptop and open the serial monitor.
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.
This videos explain a lot of details about the project fabrications.
Using technology and a hackers mindset to increase food security for the coming billions last updated 21 9 2015.
Least 4 minutes you find the testing experiment on mm 93.
So i built my smart meter model mm 93 based on arduino with some awesome features hope you like and enjoy the project.
A project log for fly wars.
Use the tcrt5000 ir barrier line track sensor.
It emits an infrared light and detects the reflection.
The code is shown in the attached images here is the link to download the energy meter code.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
There is no specific method to checkthe level of the water.
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.
And it worked well.
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.
