#BATTERY MONITOR HOW TO#

The s pin of the sensor module is connected with the analog pin of the Nodemcu esp8266 wifi module and the – pin is connected with ground of the nodemcu module. On the other side we have three male headers labeled as +…. The Voltage wire is connected with the vcc terminal and the ground is connected with the gnd terminal.

But if you want to measure voltages higher than 25volts then you can watch my tutorial on how to modify this voltage sensor for monitoring higher voltages, in this tutorial I performed all the calculations.Īs you can see on one side we have a block terminal, this is where we connect the voltage and ground wires coming from The battery, solar panel or any other source. This is the Voltage sensor Module that we will be using today, This Module is capable of measuring the voltages ranging from 0.02445v to 25volts dc.

I would appreciate your support in this way! I may make a commission if you buy the components through these links. Blynk application designing and finally.The battery voltage is displayed on the Gauge while the loads are controlled using the Numeric input buttons which I will explain in a minute.

This is an IoT “internet of things” based project and is entirely based on the Nodemcu esp8266 wifi module and Blynk application. In this tutorial, 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.
