Description:
**********************
In today’s episode, we will be monitoring the battery voltage wirelessly using a Bluetooth module HC-05 or HC-06, Arduino Uno or Mega, and an android cell phone. This project can also be used to monitor solar panels, in fact, you can monitor anything so far the voltage that is to be monitored is less than or equal to 25volts. Let's Get started.
This is the Voltage sensor Module that we will be using today, This Module is capable of measuring the voltages ranging from 0.02445v to 25volts dc. But if you want to measure voltages higher than 25volts then you can watch my tutorial on how to modify this voltage sensor for monitoring higher voltages, in this tutorial I performed all the calculations. I will provide a link in the description.
As you can see on one side we have a block terminal, this is where we connect the voltage and ground wires coming from The battery, solar panel or any other source. The Voltage wire is connected with the VCC terminal and the ground is connected with the ground terminal.
On the other side, we have three male headers labeled as +…. , s…. and -. ……
the s pin of the sensor module is connected with the analog pin of the Arduino Uno or mega and the - pin is connected with ground of the Arduino. while the + pin is not connected.
as in the beginning, I said that we can measure dc voltages ranging from .02445volt to 25volts. Now the question is how we know that the input voltage should be greater than .02445volts.

Thank you for breaking down the math into language I can understand!!!!
Good project Thank You Sir
Good project but I need one more thing to add on.
1. One SD card is needed for data store.
2. Full coding and circuit diagram
3. Need to 5 channel battery data logger .
What would i need to change if i wanted to monitor voltage and amperage of a 12 Volts emergency lights lights in my garage. If the amperage is more tham milli amps? Should i just increase the size of the resistors for the heat of the higher amperage??? thanks
watch my tutorial on load monitoring and protection.You need to add only current sensor. nothing else..
that sensor can handle more than 20 amps. watch that tutorial, that will really help you. i have practically test that, and have used it in so many projects. you can also use other current sensors which can handle more amps.
and watch my tutorials on nodemcu you as well, if you want to monitor and control your emergency lights from anywhere around the world.
if you face any problems let me know over here, or you can text me on my whatsapp number.
Is that sensor can measure under 1 volt ? Lets say, i want to measure current with range -950 mV to -1.250 mV.
what if we want to plot the voltage in graph instead?
I would like to do the same thing but set a high and low value to trigger alarm event and send me a text.
Can I use iPhone or Laptop to collect data from the battery. I need help with that and email you today for that. I do not have Android cell phone. Thank you
Bro i want to understand why we only include 30k and 7.5k resistance
Thank you this is a nice project, im doing something similar, in stead of a voltage sensor im using a current sensor, i need to compare, two sesnor values from two bluetooth module, slave and master, i need to measure, display on an LCD both the currents and compare, if the slave the current is less than i need to send an sms, could you please assist if you can
watch my videos on 3 phase transformer, in which i used multiple current sensors
I made this circuit for school but now i want to change something in the code so the voltage is showed on the app in percentages, we are measuring a lead acid battery and online there are converting tables to go from voltages to percentages but i don't know how to code this in the arduino, hopefully someone can help.
Wifi battery monitor both volt and current, is it possible
List device name used in battery voltage logging system ??( Plzz give me answer of this question)
hc05 bluetooth, 0-25v voltage sensor, Arduino uno or Nano.
you can also watch my latest video on the same topic, thats the long range
What about the Android app.did u design it or its available on the playstore??
You can download from playstore.
But the one i use, i design jt myself.
Gr8.why not starting tutorial on Android app development. Also u need to write a name of App( APK File) and a link in video and description
I will start a tutorial series on android, but just waiting for monetization
I will be adding thousands of projects, covering all fields of engineering
Gr8.u r Geniius bro.will b waiting for all topics.i really enjoy watching your videos.
Do you think a person goes by a voltage on bluetooth as a name
Dear sir, how many distance to we have see that voltage from blue tooth device......please give answers VERY nessary required.
you can find this in the bluetooth module datasheet.
the one i used has 10 to 15meters range.
Dear sir i want to see/monitering from 20 kilometer distance of blue tooth devices.....how it possible.
20 km is such a long range. Then u should use gsm or wifi.
Watch my tutorials on gsm and wifi
Hello sir I am using your code but it shewing an error 'PinMode' was not declared in this scope. how to solve this...Please help
this is "pinMode" not "PinMode".
The link for the code and circuit diagram is not working. Can you please fix it.
we are working on the website. it will available in a day or two.
Why my output is 19v instead of 12v only ?
Use the calibration value.
And measure the actual output of the battery with dmm.
Then compare both the values and set the calibration factor value accordingly
Where did you connect the two resistors ?
Application?
Bro, the project link is not working. Can you fix that.
The website is online now.
But using Bluetooth it is only 1-1 connection. If I have more batteries it will not work
for multiple batteries i used another technique watch my latest video
@@ElectroniClinic I saw it but unless each Rf module has its own microprocessor, it is way too big to fit in a battery.
@@Island728 you can reduce the size. i made a large development board, but you can reduce the overall size
code link bro
It's available on electroniclinic.com
