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.
