The code is shown in the attached images here is the link to download the energy meter code.
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.
Arduino hall effect water flow meter.
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.
So it can be so helpful to hang a picture.
This videos explain a lot of details about the project fabrications.
The ph of pure water is 7.
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.
Least 4 minutes you find the testing experiment on mm 93.
The project under discussion has the capability to checkthe water level and also send the data over wifi.
A hackers solution to world hunger.
This a project i ve been working for some time now.
And it worked well.
The solution was a 15 meter length of four conductor.
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.
Using technology and a hackers mindset to increase food security for the coming billions last updated 21 9 2015.
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.
Connect arduino with the laptop and open the serial monitor.
It emits an infrared light and detects the reflection.
Use the tcrt5000 ir barrier line track sensor.
To check the water level ultrasonic hc sr04 is the distancesensor.
In general water with a ph lower than 7 is considered acidic and with a ph greater than 7 is considered basic.
The idea is to make a sensor which can sense the water levelin tanks where the motor pumps are used.
So the water under.
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.
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.
