Pin Configuration

Voltage Sensor Module 25V Documentation
Pinout Description
The Voltage Sensor Module 25V is a compact module designed to measure voltage levels up to 25V. The module has a total of 4 pins, each with a specific function. Below is a detailed description of each pin:
Pinout Structure:
1. VCC (Power Supply Pin)
Function: Provides power to the module
Voltage Range: 3.3V to 5V
Description: Connect this pin to a stable power supply, such as a battery or a regulated power source, to power the module.
2. GND (Ground Pin)
Function: Provides a reference ground point for the module
Description: Connect this pin to the ground of your system or circuit to provide a common reference point.
3. VIN (Voltage Input Pin)
Function: Inputs the voltage to be measured
Voltage Range: 0V to 25V
Description: Connect this pin to the voltage source you want to measure. Make sure the voltage does not exceed 25V.
4. VOUT (Voltage Output Pin)
Function: Outputs the measured voltage as a proportionally scaled analog signal
Voltage Range: 0V to VCC (dependent on the input voltage)
Description: Connect this pin to an analog-to-digital converter (ADC) or a microcontroller's analog input pin to read the measured voltage.
Connection Guidelines:
To use the Voltage Sensor Module 25V, follow these connection guidelines:
1. Connect VCC to a stable power supply (3.3V to 5V).
2. Connect GND to the ground of your system or circuit.
3. Connect VIN to the voltage source you want to measure (0V to 25V).
4. Connect VOUT to an ADC or a microcontroller's analog input pin.
Important Notes:
Make sure to use a suitable power supply that meets the module's power requirements.
Ensure the input voltage (VIN) does not exceed 25V to avoid damaging the module.
Use a suitable voltage regulator or divider circuit if your voltage source exceeds 25V.
The module's output voltage (VOUT) is proportional to the input voltage (VIN). You may need to use an ADC or a microcontroller to convert the analog output signal to a digital value.
By following these connection guidelines and taking note of the important considerations, you can accurately measure voltage levels using the Voltage Sensor Module 25V.

Code Examples

### Example 1: Measuring Voltage with an Arduino Board

In this example, we will use the Voltage Sensor Module 25V to measure the voltage of a battery connected to an Arduino Uno board.

Hardware Requirements

Arduino Uno board
 Voltage Sensor Module 25V
 Breadboard and jumper wires
 Battery (e.g., 9V)

Software Requirements

Arduino IDE (version 1.8.x or later)

Code
```c
const int voltageSensorPin = A0;  // Analog input pin for voltage sensor

void setup() {
  Serial.begin(9600);
}

void loop() {
  int sensorValue = analogRead(voltageSensorPin);
  float voltage = sensorValue  (25.0 / 1023.0);
  Serial.print("Voltage: ");
  Serial.print(voltage);
  Serial.println(" V");
  delay(500);
}
```
In this code, we read the analog value from the voltage sensor module using the `analogRead()` function. We then convert the value to a voltage reading using the formula: `voltage = sensorValue  (25.0 / 1023.0)`. The result is printed to the serial console.

### Example 2: Measuring Voltage with a Raspberry Pi (Python)

In this example, we will use the Voltage Sensor Module 25V to measure the voltage of a power supply connected to a Raspberry Pi.

Hardware Requirements

Raspberry Pi (any model)
 Voltage Sensor Module 25V
 Breadboard and jumper wires
 Power supply (e.g., 12V)

Software Requirements

Raspbian OS (any version)
 Python 3.x

Code
```python
import adc  # Import the ADC library for Raspberry Pi

# Set up the ADC channel for the voltage sensor
adc_channel = 0

try:
    while True:
        # Read the analog value from the voltage sensor
        sensor_value = adc.read_adc(adc_channel)

# Convert the value to a voltage reading
        voltage = sensor_value  (25.0 / 1023.0)

print(f"Voltage: {voltage:.2f} V")
        time.sleep(0.5)

except KeyboardInterrupt:
    print("Program interrupted. Exiting...")
```
In this code, we use the `adc` library to read the analog value from the voltage sensor module. We then convert the value to a voltage reading using the formula: `voltage = sensor_value  (25.0 / 1023.0)`. The result is printed to the console.

These examples demonstrate the basic usage of the Voltage Sensor Module 25V in different contexts. You can modify the code to suit your specific requirements and integrate it into your IoT projects.
