ArduinoWhat is Arduino? A Comprehensive OverviewWhat is Arduino? A Comprehensive OverviewDive into the world of Arduino with our in-depth guide covering hardware, software, and community projects ideal for students, hobbyists, and educators. Binary Transmission (Optimized):

struct SensorPacket {
  uint32_t timestamp;
  uint16_t raw_value;
  float voltage;
};
void setup() {
  Serial.begin(115200);
}
void loop() {
  SensorPacket data;
  data.timestamp = millis();
  data.raw_value = analogRead(A0);
  data.voltage = data.raw_value * (5.0 / 1023.0);
  Serial.write((byte*)&data, sizeof(data));
  delay(10);
}

Python Binary Decoder:

import struct
fmt = '<I H f'  # uint32, uint16, float (little-endian)
packet_size = struct.calcsize(fmt)
with serial.Serial('COM3', 115200) as ser:
    while True:
        data = ser.read(packet_size)
        if len(data) == packet_size:
            ts, raw, volt = struct.unpack(fmt, data)

Sensor Calibration Math

For LM35 temperature sensorsIntroduction to Sensors for ArduinoIntroduction to Sensors for ArduinoLearn the fundamentals of Arduino sensors, including setup, calibration, and coding examples—perfect for building interactive, smart projects with precision.:

Vout=10mV/°C×T V_{out} = 10 \, \text{mV/°C} \times T
ADCvalue=Vout×1024Vref ADC_{value} = \frac{V_{out} \times 1024}{V_{ref}}

Python Real-Time Plotting:

import matplotlib.animation as animation
fig, ax = plt.subplots()
def animate(i):
    data = pd.read_csv('sensor_data.csv').tail(100)
    ax.clear()
    ax.plot(data['Timestamp'], data['Voltage'], label='Live Data')
    ax.set_xlabel('Time (s)')
    ax.set_ylabel('Voltage (V)')
ani = animation.FuncAnimation(fig, animate, interval=200)
plt.show()

Rolling Metrics

Anomaly Detection

Statistical Feature Engineering:

df['Rolling_Mean'] = df.Voltage.rolling(10).mean()
df['Delta_T'] = df.Timestamp.diff().fillna(0)
# Signal-to-Noise Ratio (SNR)
snr = 10 * np.log10(np.var(df.Voltage) / np.var(df.Voltage - df.Rolling_Mean))

byte checksum = (raw >> 8) ^ (raw & 0xFF);
Serial.print("$");
Serial.print(raw);
Serial.print("*");
Serial.println(checksum, HEX);

2. Asynchronous Python Data Collection:

import asyncio
import serial_asyncio
class AsyncSerialReader(asyncio.Protocol):
    def data_received(self, data):
        line = data.decode().strip()
        # Process data in non-blocking mode
