This IoT-based smart home project effectively combines various sensors and internet technology to create a highly functional and automated home environment, enhancing both convenience and security.
This IoT-based smart home project leverages the Adafruit.io platform to create an integrated home automation system. It enables users to monitor and control various household devices remotely through the internet. By using various sensors and actuators connected to an Adafruit IO dashboard, homeowners can automate tasks like lighting, temperature control, and security systems, enhancing convenience and energy efficiency.
Components Used
DHT11 Sensor: Measures humidity and temperature.
LDR (Light Dependent Resistor): Controls lighting based on ambient light levels.
Manual Control Buttons: Integrated in the Adafruit.io dashboard for appliances like AC and pumps.
Exhaust Fan: Automatically controlled based on temperature readings.
OLED Display: Shows real-time temperature and humidity data.
IR Sensor: Detects presence near the gate and sends data to Adafruit.io.
Working of the Project
Temperature and Humidity Monitoring:
The DHT11 sensor continuously monitors the ambient temperature and humidity.
The temperature and humidity readings are displayed in real-time on the connected OLED screen for on-site monitoring.
Data is also sent to the Adafruit.io dashboard where it can be viewed remotely.
Automatic Light Control:
The LDR sensor measures the level of ambient light.
When natural light decreases below a predefined threshold (e.g., at dusk), the LDR triggers the microcontroller to switch on the lights.
Conversely, when the ambient light level is high enough (e.g., dawn), the lights are automatically turned off.
This automation helps in energy saving and adds convenience for the users.
Manual Appliance Control:
Two buttons are provided on the Adafruit.io dashboard interface, allowing users to manually turn on or off appliances such as air conditioners and water pumps.
This feature offers flexibility, letting users override automatic settings or control devices not governed by sensors.
Temperature-Driven Exhaust Fan Activation:
If the DHT11 sensor detects that the temperature exceeds 40 degrees Celsius, the system automatically activates the exhaust fan.
This helps in maintaining a comfortable indoor environment and prevents overheating.
Security and Presence Detection:
An IR sensor is placed near the gate to detect if someone is standing there.
When presence is detected, the sensor sends a signal to the microcontroller, which then updates the status on the Adafruit.io dashboard to “1” indicating someone is at the gate.
This feature enhances security by alerting homeowners of potential visitors or intruders.
Integration with Adafruit.io
All sensor data and control signals are sent to and from the Adafruit.io platform via the internet.
Adafruit.io serves as the central hub where users can monitor environmental parameters, control devices, and receive notifications.
The platform’s user-friendly interface ensures that users can easily interact with their smart home system, customize settings, and monitor their home environment from anywhere in the world.
