Code Example: Simple IoT Data Collection and Visualization

To illustrate a basic IoT implementation, let’s create a simple example using Python to collect temperature data from a sensor and visualize it using Matplotlib. This example assumes you’re using a Raspberry Pi with a connected temperature sensor.


import Adafruit_DHT
import matplotlib.pyplot as plt
from datetime import datetime
import time

# Set up the sensor
sensor = Adafruit_DHT.DHT22
pin = 4

# Lists to store data
temperatures = []
timestamps = []

# Collect data for 1 hour
duration = 3600  # seconds
interval = 10  # seconds

start_time = time.time()
while time.time() - start_time < duration:
    # Read temperature from the sensor
    humidity, temperature = Adafruit_DHT.read_retry(sensor, pin)
    
    if temperature is not None:
        temperatures.append(temperature)
        timestamps.append(datetime.now())
        print(f"Temperature: {temperature:.1f}°C")
    else:
        print("Failed to read temperature")
    
    time.sleep(interval)

# Visualize the data
plt.figure(figsize=(12, 6))
plt.plot(timestamps, temperatures)
plt.title("Temperature over Time")
plt.xlabel("Time")
plt.ylabel("Temperature (°C)")
plt.gcf().autofmt_xdate()
plt.grid(True)
plt.savefig("temperature_plot.png")
plt.show()

This script collects temperature data every 10 seconds for an hour and then creates a plot of temperature over time. The resulting graph is saved as an image file and displayed on screen.
