Air pollution is a growing concern worldwide, affecting both outdoor and indoor environments. Monitoring air quality is the first step toward creating healthier living spaces. This article will guide you through building your own home air quality monitoring system, capable of measuring temperature, humidity, and Carbon Dioxide (CO2) levels.
Why Monitor Air Quality?
Poor air quality can lead to a range of health issues, including respiratory problems and allergies. An air quality monitoring system can provide real-time data, helping you take immediate action to improve your living conditions.
To build this air quality monitoring system, you’ll need the following components:
- PIC Microcontroller
- Temperature and Humidity Sensor
- CO2 Sensor
- LCD Display
- Basic Electronic Components (Resistors, Capacitors, Transistors)
- Cables and Connectors
- PCB and Breadboards
- MC Programming Language: C
How It Works
The system uses sensors to measure the levels of CO2, temperature, and humidity both inside and outside your home. These sensors are connected to a PIC microcontroller, which processes the data and displays it on an LCD screen. This allows you to monitor the air quality in real-time and take necessary actions to improve it.
Setting Up the System
- Connect the Temperature and Humidity Sensor, and the CO2 Sensor to the PIC Microcontroller.
- Attach the LCD Display to the microcontroller.
- Load the C program into the PIC Microcontroller to process the sensor data.
- Place one set of sensors inside your home and another set outside to gather comprehensive data.
Advantages of the System
- Real-time air quality monitoring
- Measures multiple parameters (CO2, temperature, humidity)
- Easy to set up and use
Building your own air quality monitoring system is a rewarding project that can significantly improve your living conditions. With real-time data, you can take immediate steps to purify your indoor environment and live a healthier life.
