Hardware Components and Setup
The system utilizes a robust array of sensors for comprehensive environmental monitoring. These include an MQ9 carbon monoxide sensor, LM35 temperature sensor, a humidity sensor, an MQ6 LPG gas sensor, and an MQ135 air quality sensor. A soil moisture sensor is also integrated for complete environmental data capture. The sensors are connected to an Arduino Uno R3 board, serving as the central processing unit.
Power is supplied via a 5V power supply module, powering the Arduino and sensors. Communication is facilitated by a GPRS module (SIM900) for data transmission to a remote server. An LCD display provides real-time feedback on sensor readings. The Max232 board acts as a crucial level converter, ensuring seamless communication between the Arduino and the GPRS module.
Data Acquisition and Transmission
The Arduino continuously monitors sensor data. This data is then processed and formatted for transmission. The GPRS module, using a GSM SIM card, facilitates the transmission of environmental data to a cloud server for storage and remote access.
The system's real-time capabilities allow for immediate alerts. When pre-set thresholds are exceeded, SMS and email alerts are automatically triggered, informing users of potential environmental hazards. This ensures timely intervention, preventing potential problems.
Web Interface and Data Visualization
A user-friendly web interface allows for remote monitoring of environmental parameters. Real-time sensor data is presented in a clear and intuitive manner, enabling users to track environmental conditions remotely. This provides valuable insights into environmental trends and potential risks.
The web interface displays temperature, humidity, soil moisture, and gas sensor readings. Historical data can be accessed to analyze environmental trends and patterns over time, facilitating informed decision-making. This comprehensive data visualization tool makes the monitoring system highly effective.
Conclusion and Evaluation
This IoT-based environmental monitoring system effectively integrates various sensors and communication technologies for real-time environmental monitoring. Its ability to provide real-time data, generate alerts, and offer remote access makes it suitable for a variety of applications. The system's user-friendly interface and reliable performance are key strengths.
The system’s responsiveness to environmental changes and the timely alerts greatly improve safety and efficiency. The modular design allows for customization and expansion. While there may be other similar systems available, this one stands out due to its robust features and ease of use.
