Detailed Description:

Precisely monitor DC voltage levels in your electronic projects with our reliable DC Voltage Sensor Module 1V-25V – Analog Voltage Detection Module. This compact and essential component is designed to safely step down higher DC voltages, allowing your microcontrollers, such as Arduino, Raspberry Pi, ESP32, or other low-voltage systems, to accurately measure them without risk of damage.

The DC Voltage Sensor Module operates on the principle of a resistive voltage divider circuit. It typically uses two precision resistors (e.g., a 30KΩ and a 7.5KΩ resistor) to reduce the input voltage by a fixed ratio (commonly 5:1). This means that a maximum input of 25V DC will be scaled down to a safe 5V DC output, which is perfectly within the analog input range of most popular microcontrollers. This simple yet effective design ensures accurate and stable voltage readings.

Key features of this analog voltage detection module include:

• Wide Input Voltage Range: Capable of measuring DC voltages from 1V up to 25V, making it suitable for monitoring various battery types (e.g., 3.7V Li-ion, 12V lead-acid), power adapters, and system power lines.

• Analog Output: Provides a linear analog voltage output (e.g., 0-5V or 0-3.3V, depending on your microcontroller's ADC reference) that is directly proportional to the measured input voltage. This allows for straightforward interpretation and integration into your code.

• Safe Interfacing: Protects your sensitive microcontroller's Analog-to-Digital Converter (ADC) from high voltages that could otherwise cause permanent damage.

• Compact Design: Small footprint with convenient screw terminals for easy and secure wiring of your input voltage, and standard header pins for connecting to your microcontroller.

• Ease of Use: Requires no complex libraries; the voltage reading can be obtained with a simple analogRead() function and a scaling calculation in your microcontroller code.

Common applications for our DC Voltage Sensor Module include:

• Battery Monitoring Systems: Track the charge level and health of battery packs in portable devices, robotics, or solar power systems.

• Power Supply Regulation: Provide feedback for power management circuits, ensuring stable voltage output.

• Over/Under-voltage Protection: Trigger alerts or cut off power if voltage levels fall outside a safe operating range.

• DIY Voltmeters: Build custom digital voltmeters for various applications.

• Robotics & Automation: Monitor motor voltages, sensor power, or overall system voltage in mobile robots and automated machinery.

Equip your projects with the ability to precisely sense and respond to voltage changes.

This voltage sensor module uses a resistive voltage divider to reduce input voltage by a fixed ratio, making it readable by the ADC of Arduino, ESP32, STM32, etc. It can safely measure input voltages up to 25V DC, mapping them to a 0–5V analog output.
