Project Description:
********************
In today’s episode, you will learn how to monitor the Battery voltage from anywhere around the world and control DC light bulbs and other dc loads using 12v SPDT type relays. This is an iot “internet of things” based project and is entirely based on the Nodemcu esp8266 wifi module and Blynk application. these are the two wires which are coming from the 12v Battery, these wires are connected with the digital multimeter and also with the voltage sensor. This tutorial covers
1. Voltage sensor pinout and calculations
2. Complete circuit diagram
3. Blynk application designing and finally
4. Testing

Very good work bro.
Adc max volt is 3.3 Volt for some boards
So change the resistance and code accordingly
1-5V from transmitter .
I need to configure 0- 100% level on blynk app
How its possible?
Can the voltage accuracy be increased to one decimal place?
Hello how to measure 55v dc ,can it works with this?
Great video, thank you.
Do you know if a 0-100v sensor exist? I cannot find one. I'm ideally looking for a range between 42v and 60v for a 14s battery. I'd like to use one sensor for the whole battery and not need to wire up 14 sensors
i have a video in which i have explained how to monitor 220vac, you can follow that video and make a sensor for any voltage.
@@ElectroniClinic Thanks man
how can i build a system and connect 15 samples of MFC (microbial fuel cell)(it is almost like a battery, they produce electric) in same time for measuring current (low between 0mA to 3A) and voltage (between 0mV to 800 mV) continuously? I have an oscilloscope, if the system help me to get the reading continuously from the oscilloscope or independently measure them, both way is good for me. Please someone help me.
Please share the link for code understanding.in Playlist lotoff vdo i can't find.
Can you make for 60v dc?
can u help me do a 2 way audio communication system iot to blynk app
Can I use the lead acid battery (battery used in inverter ) in this project?
Yes why not
I need 10 pieces of these, how much it would cost if you do this for me?
Sir I have using water tank level transmitter for measuring the tank level. The transmitter out is 1 to 5 V variable
Means
1V need to set 0%
2V need to set 25%
3V need to set 50%
4V need to set 75%
5V need to set 100%
Can you make gauging display via blynk app with modemcu
Please make code for me
can this project measure AC voltage like car battery(lead acid) ???
Car batteries are DC, not AC so yes as long as its less then 25V DC this project will work.
can I use the push button to replace numeric input?
yes
Can u get it to measure the Percentage in the battery
yes of course. you can watch my video, in which I used led's to display the percentage of battery. actually, the voltage tells you how much charge is available. in this project, you only need to use the if conditions.
Electronic Clinic I am new to all this stuff so can you please make the code for a nodemcu to tell me how much percentage is left in my 12 volt battery on my blynk app
But how to get the current I value?
Watch my video on load monitoring
Dear sir how we knowing 3 different battery data from 3 different area with blynk app.
Use same authentication token
sir, I want see 3 battery voltage data with In 1 blynk aap, is it possible.
Yes my dear. You will use the same authentication token in all nodemcu programs. But use differet virtual pins .
This only wifi Or over internet ?
iot
How it measure over 12 VDC,can it work ?
check playlists
@@ElectroniClinic what's name playlist it ?
Great Scott audio. Not good
please send me project code
Code is available on my website. Check description
