Voltage Detection Sensor Module DC 0 To 25V

The Voltage Sensor DC 0-25V Module is designed to measure DC voltages between 0 and 25V. It is commonly used with microcontroller platforms like Arduino to safely measure higher voltages by stepping them down to a range that can be read by the microcontroller's analog-to-digital converter (ADC).

Specifications:

• Input Voltage Range: 0V to 25V DC
• Output Voltage Range: 0V to 5V (output to the analog pin of Arduino)
• Voltage Divider Ratio: 5:1 (the input voltage is divided by 5)
• Analog Input Compatibility: Works with Arduino, ESP8266, ESP32, and other 5V/3.3V compatible devices.
• Measurement Accuracy: +/- 1%
• Maximum Input Voltage: 25V DC (do not exceed this limit)
• Operating Temperature: -40°C to 85°C

Features:

1. Voltage Divider Circuit: The module contains a voltage divider that steps down the input voltage by a factor of 5. This allows the Arduino to measure higher voltages while keeping the input voltage on its ADC pin within the safe 0-5V range.

2. Simple Design: It has a very straightforward design with two screw terminals for connecting the voltage to be measured and a pin header for connecting to the microcontroller.

3. High Precision: The resistor values used in the voltage divider are carefully selected for precision voltage measurement with minimal error.

Pinout:

• VCC (+): Connect this pin to the positive terminal of the voltage source you want to measure (up to 25V DC).
• GND (-): Connect this pin to the ground terminal of the voltage source.
• S (Signal Output): This is the analog signal output pin that you connect to an analog input pin on the Arduino (e.g., A0).
• GND (-): Connect to the Arduino's GND to complete the circuit.

Applications:

• Battery voltage monitoring (e.g., 12V battery systems)
• Power supply voltage measurement
• Monitoring and regulating solar power systems
• General voltage measurement in electronics projects
