Connect arduino with the laptop and open the serial monitor.
Arduino water meter reader.
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.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
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.
The idea is to make a sensor which can sense the water levelin tanks where the motor pumps are used.
In general water with a ph lower than 7 is considered acidic and with a ph greater than 7 is considered basic.
In some cases newer water meters are equipped with a pulse output.
So i built my smart meter model mm 93 based on arduino with some awesome features hope you like and enjoy the project.
Use the tcrt5000 ir barrier line track sensor.
It emits an infrared light and detects the reflection.
A hackers solution to world hunger.
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 ph of pure water is 7.
To check the water level ultrasonic hc sr04 is the distancesensor.
The project under discussion has the capability to checkthe water level and also send the data over wifi.
This videos explain a lot of details about the project fabrications.
There is no specific method to checkthe level of the water.
So it can be so helpful to hang a picture.
Least 4 minutes you find the testing experiment on mm 93.
This a project i ve been working for some time now.
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.
Arduino hall effect water flow meter.
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.
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 code is shown in the attached images here is the link to download the energy meter code.
Using technology and a hackers mindset to increase food security for the coming billions last updated 21 9 2015.
And it worked well.
