![]() These functions are generated with the Thing and added at the end of this sketch. Which are called when their values are changed from the Dashboard. Variables which are marked as READ/WRITE in the Cloud Thing will also have functions The following variables are automatically generated and updated when changes are made to the Thing Sketch generated by the Arduino IoT Cloud Thing "Battery Monitoring" Now, simply compile and upload the code to your NodeMCU board. Simply, copy and paste the code provided below. Go back to the Things Tab then click on the sketch. The user can check the battery status on their smartphones or Computer Dashboard from anywhere in the world. now due to the use of the Internet of Things, we can directly notify the users remotely. But in this project, we have used the Internet of Things( IoT) technology which can directly notify the users remotely. The BMS can only monitor the condition of the battery and alarm the user through a battery indicator. To ensure the proper safety and handling of Lithium-Ion or Lithium Polymer batteries. Actually, BMS monitors all the properties of the battery like the voltage, current, temperature & auto cut-off system. Most of the electrical/electronics devices have a Battery Management System ( BMS). We all know that an improper system of charging and discharging may lead to battery damage or system failure. Hence, we need to monitor the voltage level of the battery. Therefore, this system is useful for monitoring battery charging /discharging status remotely.Īs we know, the battery in any system or device is the main component because it powers the entire system. Using this system we can monitor battery voltage and percentage from anywhere in the world. In this project, we will build a Battery Status Monitoring System using ESP8266 & Arduino IoT Cloud.

By measuring the voltage across this resistor at regular intervals during the discharge process it is simple to calcuate the total energy dissipated and therefore the total energy which had been stored in the battery. In order to measure the stored energy in a battery a power resistor is used as the load, and a fully charged battery is fully discharged through it. Stored energy is measured in Watt-hours - the same unit used to measure our domestic electricity consumption (where 1,000Wh = 1kWh = 1 unit of electricity). When measuring the real battery capacity what we are interested in is the amount of energy stored in a battery since it is this energy we need to power our devices.
