Study Notes
- The project aims to create a compact and efficient system for environmental conditions using an ESP8266 board and sensors like DHT11, MQ135, and an LDR sensor.
- The goal builds a Smart Environment Monitoring System to measure and report temperature, humidity, air quality, and light accurately.
- Data collected from these sensors will be used for weather forecasting, environmental monitoring, or personal weather tracking.
Components of an environment monitoring system
- ESP8266 Board acts as the central control unit, handling data collection from sensors and connecting to the internet via Wi-Fi for data transmission to a remote server or cloud platform.
- DHT11 Sensor measures temperature and humidity.
- MQ135 Sensor detects various gases and helps assess air quality.
- LDR Sensor detects changes in light intensity.
- Power supply, connecting wires, and a breadboard are required for setup.
System Functions
- Data Collection: The ESP-8266 reads data from the DHT11 sensor for temperature and humidity values, the MQ-135 sensor for air quality data, and the LDR sensor for Light Intensity information.
- Data Transmission: After collecting the sensor data, the ESP8266 uses its Wi-Fi capability to send this data to a remote server or a cloud platform for storage and analysis.
- Include a monitoring interface using a web application
Application in Smart Agriculture
- Optimizing Irrigation: The Smart Environment Monitoring System can provide real-time data on temperature, humidity, and light to determine the moisture level in the soil.
- The MQ135 sensor in the Smart Environment Monitoring System can detect gases like ammonia and nitrogen oxides, which are crucial for assessing air quality.
- Crop Disease Prevention: Certain environmental conditions, such as high humidity or stagnant air, can contribute to the spread of crop diseases. The Smart Environment Monitoring System can alert farmers to conditions conducive to disease development.
