If you want to learn how to modify this sensor to measure higher voltages greater than 200 volts then watch my tutorial. The S pin of the sensor module is connected with the analog pin of the Arduino or mega and the – the pin is 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. As you can see on one side we have a block terminal, this is where we connect the voltage and ground wires coming from a battery. This module is capable of measuring the voltages ranging from 0.02445v to 25volts dc. This is 0 to 25v voltage sensor, which I will use for measuring the Battery voltage. 0-25v Voltage Sensor used in Battery Efficiency Monitoring System: Out of these 6 Pins, we will be using only 4 Pins which are the SCL, SDA, VCC, and GND. This Module can be powered up using 3.3 volts or 5 volts.Īs you can see clearly in the picture above, the DS3231 module has a total of 6 male headers and are clearly labeled. The RTC DS3231 module also has automatic compensation for leap years and for months with fewer than 31 days. This module can also maintain the day, month and year information. The RTC DS3231is a low-cost, highly accurate Real Time Clock, which can maintain hours, minutes, and seconds. For the best understanding read article on the RTC DS3231 given in the related projects section. Arduino is really powerful and we can make a real-time clock, but the problem comes in when the Arduino is turned off, or the power is disconnected, the time and date information is completely lost.īut if you look at the RTC DS3231 module it has a battery and can keep track of the Time and Date information even if the main power supply is disconnected or we reprogram the microcontroller. You might be thinking why we need the RTC DS3231 module when the Arduino itself has the built-in timekeeper. I would appreciate your support in this way! I may make a commission if you buy the components through these links. Without any further delay, let’s get started.

In this project, I used the same 0 to 25-volt voltage sensor and the same HC-05 Bluetooth module. This project is entirely based on my previous Tutorial based on the wireless battery voltage monitoring system. Currently, I am using only the Voltage sensor for demonstration purposes. More sensors can be connected with the Arduino.

The information stored in the database can be used for post-analysis.

The received information is stored in the Cell Phone database along with the Date and Time information.

Then using the Android Cell Phone the stored information can be requested wirelessly by sending a command to the Arduino. The Battery voltage information is stored in the Arduino at regular intervals which can be defined in the Programming.
