Interfacing and Code Examples

### Example 1: Arduino-based Current Measurement

Connect the sensor's output to an analog input pin of an Arduino board. Use the following code to read the current value:
```c++
const int sensorPin = A0;  // Analog input pin
const float sensitivity = 100.0;  // mV/A
const float voltageRef = 5.0;  // V

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

void loop() {
  int sensorValue = analogRead(sensorPin);
  float voltage = sensorValue  (voltageRef / 1023.0);
  float current = voltage / sensitivity;
  Serial.print("Current: ");
  Serial.print(current, 2);
  Serial.println(" A");
  delay(1000);
}
```
This code reads the analog voltage output from the sensor, converts it to a digital value, and calculates the current using the sensitivity value.

### Example 2: Raspberry Pi-based Energy Monitoring

Connect the sensor's output to an analog input pin of a Raspberry Pi (e.g., GPIO 18). Use the following Python code to read the current value and calculate energy consumption:
```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.IN)

sensitivity = 100.0  # mV/A
voltage_ref = 3.3  # V

while True:
    sensor_value = GPIO.input(18)
    voltage = (sensor_value  voltage_ref) / 1023.0
    current = voltage / sensitivity
    power = current  230.0  # assuming 230V AC
    energy_consumption = power  0.1  # calculate energy consumption in Wh
    print(f"Current: {current:.2f} A, Power: {power:.2f} W, Energy: {energy_consumption:.2f} Wh")
    time.sleep(1)
```
This code uses the RPi.GPIO library to read the analog input, calculates the current value, and estimates the power and energy consumption based on the measured current.

Additional Information

The 100A YHDC Non-invasive AC Current Sensor requires a 5V DC power supply, which can be provided by an external power source or a USB connection (if connected to a USB-enabled device).
 Ensure proper insulation and electrical safety when working with AC circuits.
 For accurate measurements, the sensor should be installed in close proximity to the current-carrying conductor and in a location with minimal electromagnetic interference.

By following these examples and considering the technical specifications, you can effectively integrate the 100A YHDC Non-invasive AC Current Sensor into your IoT applications.
