Hence we have to form a voltage divider network to lower down the input voltage. The ESP8266 Chip can only support the input analog voltage of 3.3V. The MCP73831 IC can also be used instead of TP4056. You can use the TP4056 module to charge the battery as its best suited for Battery Management Applications. This WiFi chip can connect to the WiFi network and uploads the data regularly to the server. You can also use the NodeMCU ESP8266 Board.

For the microcontroller, we use Wemos D1 Mini which has an ESP8266 wifi-enabled chip. We will design a system to monitor this battery voltage along with charging and discharging status. However, there are also batteries available with a cut-off voltage as low as 2.5V. The battery I frequently use has a discharge cut-off voltage of 2.8V. Manufacturer datasheets usually state the cut-off voltage to be around 3V, though this can vary based on the battery type and its specific applications. When fully charged, their maximum voltage can reach up to 4.2☐.5V. Typically, Lithium-Ion batteries have a nominal voltage of 3.7V. Some of these batteries come with an attached Battery Management System Circuit, providing over-voltage protection, balanced charging, and short-circuit protection. I’ve been using several Lithium-Ion batteries for quite some time across multiple projects. The batteries have a high energy density, no memory effect and low self-discharge. Li-ion batteries use an intercalated lithium compound as the material at the positive electrode and typically graphite at the negative electrode. In this battery, lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge, and back when charging.

Lithium-ion batteries are commonly used for portable electronics and electric vehicles. S.N.Ī lithium-ion battery or Li-ion battery is a type of rechargeable battery. You can purchase all the components online from Amazon. You will need the following components for the IoT Based Battery Monitoring System Project. In case you wanna monitor a Lead-Acid Battery, you can check 12V Battery Monitoring System project. A very precise version of this project can be checked at DIY LiPo Charger with IoT Battery Voltage Monitor, as this contains a customized PCB baord. The Thingspeak will display the battery voltage along with the battery percentage in both the charging and discharging cases. In this IoT-based Battery Monitoring System, we will use Wemos D1 Mini with ESP8266 Chip to send the battery status data to ThingSpeak cloud. They can check the battery status on their smartphones or Computer dashboards from anywhere in the world. But now due to the use of the Internet of Things, we can directly notify the users remotely. This ensures the safety and proper handling of Lithium-Ion or Lithium Polymer batteries.Įarlier BMS only monitors the condition of the battery and alarms the user via a battery indicator. The BMS monitors all the properties of the battery like the voltage, current, temperature & auto cut-off system. Most of the electrical/electronics devices has a separate system called Battery Management System (BMS). So, it is important to monitor the voltage level of the battery as improper or excess charging/discharging may lead to damage to the Battery or System Failure. In this project, we will build an IoT based Battery Monitoring System using ESP8266 where you can monitor the battery charging/discharging status along with Battery Voltage & Percentage.Īs we know, the battery is the most important component for any device as it powers the entire system.

Overview: IoT Based Battery Monitoring System using ESP8266.Usually, cloud storage requires a monthly fee. There's cloud storage, which sends your video footage to a remote server to be saved, and local storage, which relies on a separate accessory or piece of hardware, usually a microSD card, to hold any footage you'd like to save. You have two main options and picking one is up to your personal preference. It's important that the camera has crisp, clear video footage or even night vision, so you don't get stuck with grainy and unusable footage. Wireless security cameras and video doorbells are often exposed to direct sunlight, weather and other natural elements, but many others are installed under porches, near shady trees and in all sorts of other settings. Amazon Alexa, Google Assistant and Apple HomeKit are the main ones you need to look for. Nowadays, home security cameras are expected to work with at least one major smart home platform. Does it work with smart home platforms? If so, do the smart features work well together?
