The DC voltage sensor is a compact and versatile module, designed to be easily integrated into Arduino projects and other compatible development platforms. The module allows measuring continuous voltages in the range of 0-25VDC, offering a resolution of 0.00489V and a minimum detectable voltage of 0.02445V, making it suitable both for battery monitoring applications and for real-time measurement systems.
It is powered directly from the development board, accepting voltages between 3.3 and 5VDC, eliminating the need for an additional external power source. Due to its small size of 25 x 13 mm, the module integrates easily into projects with limited space.
A popular use case is the combination with an LCD screen with I2C interface, which allows displaying the measured voltage value in real time directly on the display, without complex additional components.
Specifications:
Compatibility: Arduino, 3.3V and 5V development platforms
Power supply voltage: 3.3 - 5VDC
Measured voltage: 0 - 25VDC
Resolution: 0.00489V
Minimum detected voltage: 0.02445V
Dimensions: 25 x 13 mm
Pinout:
| Pin | Function |
|---|---|
| + | Power supply 3.3 - 5VDC |
| - | GND (ground) |
| S | Analog signal output (Arduino analog pin) |
Usage:
Connect the "+" pin of the module to the 3.3V or 5V pin of the Arduino board.
Connect the "-" pin of the module to the GND of the Arduino board.
Connect the "S" pin to an analog pin of the Arduino board (e.g., A0).
Connect the voltage to be measured to the input terminals of the module, respecting the polarity.
Upload the test code to the board and open the Serial Monitor to view the read values.
Optionally, connect an LCD module with an I2C interface to display the voltage directly on the screen in real time.
