Let’s perform calculations for this circuit. I recommend you should watch this tutorial for the best understanding.Īs you can see the values of the resistors used in this module are 30k and 7.5k. A few days back I uploaded a tutorial on Electronics Voltage Divider Circuit Basics, Practical use of Voltage divider, Datasheet & calculation. It simply consists of two resistors connected in series, which makes a voltage divider circuit. Let’s have a look at the circuit diagram of the voltage sensor, The input voltage of this module should be more than. The maximum Arduino analog input voltage is 5 VĪrduino AVR chip has 10 bit AD “Analog to digital converter” So Now the question is how we know that the input voltage should be greater than. while the + Pin is not connected.Īs in the beginning, I said that we can measure dc voltages ranging from. The S Pin of the sensor module will be connected with the analog Pin of the Arduino Uno or Mega and the – Pin will be connected with the ground of the Arduino. On the other side, we have three male headers labeled as +, s and. The Voltage wire is connected with the VCC terminal and the ground is connected with the GND terminal. You can find that video on my YouTube channel.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.

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. This is the Voltage sensor Module that we will be using for monitoring the battery voltage, 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.

This time I made a few changes, I added the long-range NRF24L01 Transceiver modules to increase the range.ĭownload the Bluetooth App: BlueserialApp battery Recently I uploaded another article on the battery voltage monitoring system “ Long Range Wireless Battery Voltage Monitoring System using NRF24L01 and HC05 Bluetooth“. This wireless battery voltage monitoring system can also be used for monitoring the Solar Panels, in fact, you can monitor anything so far the voltage that is to be monitored is less than or equal to 25volts.

PLEX controller PLEX is a development board using the Arduino UNO bootloader to be easily programmed by the Arduino.

24V was chosen because battery voltage can spike up and 24V would be a safe voltage to regulate from. To allow the voltage to be read a voltage divider needed to be used to convert max 24V to 1V. The ADC in the ESP-12E can only read voltages from 0V to 1V. By using the ohms law, the data can be converted into a voltage value across a resistor. The battery monitor can log up to 3 days before starting to overwrite the oldest logged data. If the monitor is offline, the device will store the voltage against the time of the reading and will attempt to resend it later. The battery monitor works by getting the battery voltage and send it to the database. This battery monitor will help keep track of the voltages while the car is off and running. I think the alternator is not charging the battery properly or the battery is not accepting the charge. I made this to try and debug a power problem within my car. This is Wifi battery monitor that can log/store battery voltage and send the data to a database.
