Connect arduino with the laptop and open the serial monitor.
Arduino water meter reader.
This a project i ve been working for some time now.
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.
It emits an infrared light and detects the reflection.
To check the water level ultrasonic hc sr04 is the distancesensor.
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.
Use the tcrt5000 ir barrier line track sensor.
So it can be so helpful to hang a picture.
A hackers solution to world hunger.
The ph of pure water is 7.
The idea is to make a sensor which can sense the water levelin tanks where the motor pumps are used.
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.
A project log for fly wars.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
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 project under discussion has the capability to checkthe water level and also send the data over wifi.
The code is shown in the attached images here is the link to download the energy meter code.
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.
In general water with a ph lower than 7 is considered acidic and with a ph greater than 7 is considered basic.
So i built my smart meter model mm 93 based on arduino with some awesome features hope you like and enjoy the project.
And it worked well.
So the water under.
In some cases newer water meters are equipped with a pulse output.
The solution was a 15 meter length of four conductor.
Arduino hall effect water flow meter.
There is no specific method to checkthe level of the water.
