DC Voltage Sensor

SENSING PRINCIPLE: The voltage sensor module works on a resistive voltage divider principle, reducing the input voltage by a fixed factor so that higher voltages can be safely measured using a microcontroller’s analog input.
SENSOR STRUCTURE: The module contains precision resistors arranged as a voltage divider along with screw terminals and header pins for easy connection to external circuits and microcontrollers.
PIN CONFIGURATION: VCC (Input positive voltage), GND (Input ground), S/AO (Analog signal output to microcontroller).
OUTPUT SIGNAL: Provides an analog voltage output equal to one-fifth of the input voltage, enabling safe measurement using microcontroller ADC pins.
OPERATING RANGE: Designed to measure DC voltages from approximately 0.024 V up to 25 V depending on the microcontroller analog reference.
MODULE DIMENSIONS: Compact module measuring approximately 28 mm × 14 mm × 13 mm with a lightweight design around 4 grams.
APPLICATION SCOPE: Commonly used for battery voltage monitoring, power supply measurement, solar panel voltage monitoring, embedded system diagnostics, and general DC voltage measurement applications.
