To test the working of the sensor, I used 3 different types of batteries and observed the voltage on the Serial Monitor. Connect the Signal (S) and Negative (-) pin of Voltage Sensor to Arduino A0 & GND pin respectively. Let us learn interfacing of Voltage Sensor Module with Arduino. Interfacing 0-25V DC Voltage Sensor Module with Arduino If the controller has 3.3V systems, the input voltage should not be greater than 3.3Vx5=16.5V.Īrduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of the input voltage detection module is 0.00489Vx5=0.02445V. Hence you can use this module easily with Arduino. The Arduino analog input pin accepts voltages up to 5V. The internal circuit diagram of the Voltage Sensor Module is given below.

Hence the output voltage is reduced by a factor of 5 for any input voltage. The Voltage Sensor is basically a Voltage Divider consisting of two resistors with resistances of 30KΩ and 7.5KΩ i.e. Voltage Sensor Module Design & Construction

S: Analog pin connected to Analog pin of the microcontroller.GND: Negative terminal of the External voltage source.VCC: Positive terminal of the External voltage source (0-25V).The voltage sensor module has 5 pins, 2 on the front side and 3 on the backside. Dimensions: 4 × 3 × 2 cm Voltage Sensor Module Pinout Voltage Detection Range (V): 0.02445 to 25Ĥ. The 0-25V Voltage Sensor Module allows you to use the analog input of a microcontroller to monitor voltages much higher than it is capable of sensing. The Voltage Sensor Module is a simple but very useful module that uses a potential divider to reduce an input voltage by a factor of 5. You can purchase all the components from Amazon. The list of materials required for this project are as follows. This voltage measurement circuit is small & portable and you can use it to detect under or over-voltage faults in electrical circuits. We will then use a small 0.96″ I2C OLED Display to observe the output voltage. In this project we will first interface the voltage sensor module with Arduino and measure the different Battery voltages. This is the reason why you can measure the voltage up to 25V using the 5V analog pin of any microcontroller. It reduces the input voltage signal by the factor of 5 and generates a corresponding analog output voltage. The voltage sensor module is a 0-25 DC voltage sensing device that is based on a resistive voltage divider circuit. Earlier, we made 0-50V DC Voltmeter to measure the output voltages & also learned about the DC−to−DC converters. In this tutorial, we will learn interfacing of 0-25V DC Voltage Sensor with Arduino to measure DC Voltages.
