ECE 5000 - Final Demonstration

In our Live Monitoring Sensor project, we utilize the DHT11 temperature and humidity sensor, an LDR and the BMP280 pressure sensor for comprehensive monitoring. The DHT11 sensor accurately measures temperature and humidity levels, providing essential data for environmental analysis. With a wide operating temperature range and high precision, the DHT11 sensor ensures reliable performance in various environmental conditions. Additionally, the BMP280 pressure sensor offers precise pressure readings, enabling accurate monitoring of atmospheric pressure changes. Both sensors are seamlessly integrated into the hardware setup, ensuring accurate and reliable data acquisition for environmental monitoring applications.

Light Intensity
A Light Dependent Resistor (LDR) is utilized in light intensity measurements due to its property of changing resistance based on the amount of light falling on it. When exposed to light, the LDR's resistance decreases, and vice versa in darkness. To measure light intensity, the LDR is incorporated into a circuit along with a voltage source and an arduino Uno. By measuring the voltage across the LDR, the intensity of light can be inferred, as brighter light yields lower resistance and thus higher voltage readings.

Temperature and Humidity Sensor
The DHT11 sensor offers accurate temperature and humidity measurements within a wide range of environmental conditions. With its compact design and low power consumption, it's an ideal choice for applications requiring real-time data monitoring, such as weather stations and HVAC systems.

Pressure Sensor
The BMP280 pressure sensor is a high-precision module designed to measure atmospheric pressure changes with exceptional accuracy. Featuring a wide pressure range from 300 hPa to 1100 hPa and an accuracy of ±1 hPa, the BMP280 delivers reliable pressure readings across various environmental conditions. Its low power consumption and compatibility with both I2C and SPI interfaces make it suitable for battery-powered and microcontrollerbased applications. From weather forecasting to altitude tracking in drones and wearable devices, the BMP280 sensor provides crucial data for a wide range of applications requiring precise pressure monitoring.
