In today's rapidly evolving technological landscape, monitoring and measuring environmental parameters have become increasingly crucial. One of the tools developed for this purpose is an air density gauge that utilizes the BMP180 and DHT22 Internet of Things (IoT) sensors. This tool is designed to provide convenience in measuring and monitoring air density with accurate results and can be compared with existing standard measuring devices.

The Importance of Environmental Monitoring

Environmental monitoring is essential for understanding and mitigating the impact of human activities on the environment. With the increasing concern about climate change, air quality, and other environmental issues, the need for accurate and reliable monitoring tools has never been more pressing. The air density gauge is a valuable addition to the arsenal of environmental monitoring tools, providing a convenient and accurate way to measure air density.

Tool Description

The design of this tool begins with the initialization of the microcontroller that regulates the port used to read data from the sensor and display the results to the LCD screen. The BMP180 sensor is tasked with measuring air pressure, while the DHT22 sensor is used to measure humidity and temperature. The measurement process takes place as follows:

Air Pressure Reading

The BMP180 sensor begins to operate by reading the surrounding air pressure in HPA units. This is a critical component of the air density gauge, as air pressure is a key factor in determining air density.

Moisture and Temperature Reading

After the air pressure is detected, the DHT22 sensor makes a reading to get the humidity value (in %) and temperature. This data is then used to calculate the air density.

User Interaction

This tool is equipped with three buttons for interaction:

Button 1: Displays the value of air pressure in units of HPA.
Button 2: Displays the value of humidity in percent (%).
Button 3: Displays the value of the air density calculated based on data obtained from the sensor.
