This Voltage Detection Module allows safe measurement of higher voltages by scaling them down for analog input compatibility with microcontrollers. Using a precision resistor divider circuit, it converts voltages up to 25V into measurable 0–5V signals. It’s commonly used for battery monitoring, solar power systems, and energy management projects. FEATURES Simple and safe voltage scaling circuit. Analog output for microcontroller ADC input. Compact, ready-to-use breakout module. Stable, accurate readings. Compatible with Arduino, ESP, and STM controllers. APPLICATIONS Battery and power-supply monitoring Energy-usage tracking systems Solar and renewable energy setups IoT-based voltage logging
