Wireless battery voltage monitoring using Arduino , Bluetooth module Hc-05 | Hc06 and voltage sensor

[@victorreppeto7050]

Thank you for breaking down the math into language I can understand!!!!

[@hyilgorre]

Good project Thank You Sir

[@avisekhbanerjee2031]

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 .

[@andrelevesque6300]

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

[@ElectroniClinic]

watch my tutorial on load monitoring and protection.You need to add only current sensor. nothing else..

[@ElectroniClinic]

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.

[@ElectroniClinic]

and watch my tutorials on nodemcu you as well, if you want to monitor and control your emergency lights from anywhere around the world.

[@ElectroniClinic]

if you face any problems let me know over here, or you can text me on my whatsapp number.

[@midelwey]

Is that sensor can measure under 1 volt ? Lets say, i want to measure current with range -950 mV to -1.250 mV.

[@farhanamin4075]

Bro i want to understand why we only include 30k and 7.5k resistance

[@abdikadiraden1234]

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

[@alexbeum7403]

I would like to do the same thing but set a high and low value to trigger alarm event and send me a text.

[@urmilamaurya3798]

List device name used in battery voltage logging system ??( Plzz give me answer of this question)

[@ElectroniClinic]

hc05 bluetooth, 0-25v voltage sensor, Arduino uno or Nano.

[@ElectroniClinic]

you can also watch my latest video on the same topic, thats the long range

[@BestTube]

What about the Android app.did u design it or its available on the playstore??

[@ElectroniClinic]

You can download from playstore. But the one i use, i design jt myself.

[@BestTube]

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

[@ElectroniClinic]

I will start a tutorial series on android, but just waiting for monetization

[@ElectroniClinic]

I will be adding thousands of projects, covering all fields of engineering

[@BestTube]

Gr8.u r Geniius bro.will b waiting for all topics.i really enjoy watching your videos.

[@AutoTechEngineeringDHAKarachi]

what if we want to plot the voltage in graph instead?

[@solarlithiumtech1431]

Wifi battery monitor both volt and current, is it possible

[@christinadeswood9900]

Do you think a person goes by a voltage on bluetooth as a name

[@thamie_ncwane5118]

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

[@ElectroniClinic]

watch my videos on 3 phase transformer, in which i used multiple current sensors

[@strife8776]

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.

[@ajayakumarmaharana5438]

Dear sir, how many distance to we have see that voltage from blue tooth device......please give answers VERY nessary required.

[@ElectroniClinic]

you can find this in the bluetooth module datasheet.

[@ElectroniClinic]

the one i used has 10 to 15meters range.

[@ajayakumarmaharana5438]

Dear sir i want to see/monitering from 20 kilometer distance of blue tooth devices.....how it possible.

[@ElectroniClinic]

20 km is such a long range. Then u should use gsm or wifi. Watch my tutorials on gsm and wifi

[@manishMed-yi9tm]

Application?

[@gokulg1322]

The link for the code and circuit diagram is not working. Can you please fix it.

[@ElectroniClinic]

we are working on the website. it will available in a day or two.

[@ricalynn5628]

Why my output is 19v instead of 12v only ?

[@ElectroniClinic]

Use the calibration value.

[@ElectroniClinic]

And measure the actual output of the battery with dmm.

[@ElectroniClinic]

Then compare both the values and set the calibration factor value accordingly

[@ricalynn5628]

Where did you connect the two resistors ?

[@arnabpal7272]

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

[@ElectroniClinic]

this is "pinMode" not "PinMode".

[@Island728]

But using Bluetooth it is only 1-1 connection. If I have more batteries it will not work

[@ElectroniClinic]

for multiple batteries i used another technique watch my latest video

[@Island728]

@@ElectroniClinic I saw it but unless each Rf module has its own microprocessor, it is way too big to fit in a battery.

[@ElectroniClinic]

@@Island728 you can reduce the size. i made a large development board, but you can reduce the overall size

[@moditjangra6213]

Bro, the project link is not working. Can you fix that.

[@ElectroniClinic]

The website is online now.

[@user-do5dm8us7f]
