  if (isnan(h) || isnan(t)) {
    Serial.println("Failed to read from DHT sensor!");
    return;
  }
  Serial.print("Humidity: ");
  Serial.print(h);
  Serial.print(" %t");
  Serial.print("Temperature: ");
  Serial.print(t);
  Serial.println(" *C");
  if(t > 30) {

You can install OpenCV using pip:

pip install opencv-python

Make sure you have connected the PIR sensor to GPIO pin 17 (you can change it if needed) and the webcam to the Raspberry Pi.

Save the code to a Python file (e.g., security_system.py).

Run the script:

python security_system.py

This script will continuously monitor the PIR sensor for motion. When motion is detected, it will capture an image from the webcam and save it with a timestamp.

IoT Weather Station

Building your IoT weather station can be an exciting and informative project. This project will focus on collecting temperature, humidity, and barometric pressure data using the Adafruit DHT22 sensor and the BMP180 sensor.

Tools and Technologies

To create an IoT weather station, you’ll need:

Project Outline

Here’s a basic Python script for data collection:

while True:
    try:
        # Read temperature and humidity from DHT22 sensor
        humidity, temperature = Adafruit_DHT.read_retry(dht_sensor, DHT_PIN)
        # Read pressure from BMP180 sensor
        pressure = bmp_sensor.read_pressure() / 100.0  # Convert to hPa
        if humidity is not None and temperature is not None:
            print(f'Temperature: {temperature:.2f}°C, Humidity: {humidity:.2f}%')
            print(f'Pressure: {pressure:.2f} hPa')
            # Send data to Adafruit IO
            headers = {
                'Content-Type': 'application/json',
                'X-AIO-Key': ADAFRUIT_IO_KEY
            }
            data = {
                'value1': temperature,
                'value2': humidity,
                'value3': pressure
            }
            response = requests.post(ADAFRUIT_IO_URL, json=data, headers=headers)
            if response.status_code == 200:
                print('Data sent to Adafruit IO successfully!')
            else:
                print('Failed to send data to Adafruit IO.')
        else:
            print('Failed to read data from sensors.')
        # Wait for some time before collecting data again (e.g., every 10 minutes)
        time.sleep(600)
    except KeyboardInterrupt:
        print('Exiting the program.')
        break
    except Exception as e:
        print(f'Error: {str(e)}')

To set up this code:

  1. Connect the DHT22 sensor to GPIO pin 4 (you can change the pin if needed) and the BMP180 sensor according to its specifications.
  1. Install the required Python libraries for the DHT22 sensor and BMP180 sensor:

pip install Adafruit_DHT Adafruit-BMP

  1. Replace ‘your_username’ and ‘your_io_key’ with your Adafruit IO username and key.
  2. Create an Adafruit IO feed named ‘weather-data’ to receive the weather data.
  3. Run the script:

python weather_station.py

This code collects temperature, humidity, and pressure data from the sensors and sends it to Adafruit IO. You can then visualize and analyze the data on the Adafruit IO platform or integrate it with other IoT platforms and services for further analysis and visualization.
