ESP8266 Monitor its Own Battery Level using Blynk IoT for Battery Powered Projects

In this project, we will build an IoT-based Projects in which ESP8266 Monitor its Own Battery Level using Blynk IoT Cloud. We can monitor the sensor data as well as battery charging/discharging status along with Battery Voltage & Percentage.

Project Description:
Here for the demonstration, we will build an IoT weather station using DHT22 Temperature & Humidity sensor, ESP8266 development board, and Blynk IoT Cloud for remote monitoring. The whole system is powered by a single 3.7V lithium-ion battery. This battery can power nodemcu boards for around 10 hours. We need to charge the battery again using the TP4056 charging module. But sometimes I forget to charge and the whole system is down. So, to overcome this problem I thought of adding a battery monitoring system to the same project.

Nice project, But can you show the battery voltage and percentage in the lcd? not only the temp and humidity

[ybijuji]

What is the purpose of the voltage divider and what if i don't make a voltage divider

[PAVANKUMARBATCHU-ne]

can we use energy from piezoelectric sensors to charge the battery ?can we show the status of battery on blynk.Please reply asap

[ayaanba]

can this be used for 60v 33 amp battrey i have an ev scooter which has limited battery status shown and want to have more stats

[sammyguevera]

Can I use LCD Display with I2C module instead of 0.96 oled display?

[keen]

Interesting project idea, but couldn't go past the first minute....the English pronunciation is unintelligible and it's exhausting trying to figure out the words.

[musiclovertv]

can u help me for my thesis project the humid and temp is not working

[prashantmahto]

I am getting error Specify id and name in the code but i have changed that also

[XMAn-npgn]

how do I lower the refresh rate of the voltage?

[moorthy.k]

Program error showing can not find blynk libraries what can I do mam
Pls help me to solve the problem

[mahabaratam]

When i use huge battery then what iam doing

[subahashsuman]

You have connected the esp8266 vin pin on board with battery output pin which have Max of 4.2 v only, how the board is running which requires 5 v at it vin pin

[kasunperera]

Is this cords still working?my app stop working resently.any one still using ths app?

[ismailsuudi]

What if the measured battery voltage is 12 Volts or 24 Volts

[musiclovertv]

why mine temperature and humidity not working

[cridr]

someone thinks is talking English ... not yet my friend .. invest in some English lessons .. HEAR how other people are pronouncing you will be great ..
