This blog post will detail how to design and implement a smart lab using a variety of sensors and IoT components, including window status sensors, fire detection systems, a fingerprint-based door lock, NodeMCU ESP8266/mesh nodes, relays, ultrasonic sensors, ESP32-CAM, and buck converters.
Components Used
NodeMCU ESP8266/Mesh Nodes: Serve as the central control units, enabling wireless communication and integration of various sensors and devices.
Relays: Control electrical devices such as lights, fans, and alarms.
Ultrasonic Sensors: Monitor the presence of objects or measure distances, useful for automated tasks.
ESP32-CAM: Provides video surveillance and monitoring capabilities.
Buck Converter: Regulates voltage levels to power the different components.
Window Status Sensors: Detect whether windows are open or closed, enhancing security and environmental control.
Fire Detection Sensors: Monitor for signs of fire, triggering alarms and notifications for safety.
Fingerprint-based Door Lock: Provides secure access control, ensuring only authorized personnel can enter the lab.IoT window status sensors
System Operation
Window and Door Monitoring: Sensors monitor the status of windows and doors, sending data to the central system. Unauthorized access or open windows trigger alerts.
Fire Detection: Fire sensors continuously monitor for smoke or heat, activating alarms and notifications if fire is detected.
Access Control: The fingerprint-based door lock ensures secure entry, logging access attempts and allowing remote management.
Environmental Monitoring: Ultrasonic sensors and ESP32-CAMs provide real-time data on lab conditions, such as occupancy and movement.
Automated Controls: Relays control lights, HVAC systems, and other electrical devices based on sensor inputs and predefined rules.
Data Integration and Alerts: NodeMCU ESP8266/mesh nodes integrate all sensor data, providing a centralized interface for monitoring and control. Alerts are sent via email or SMS in case of any anomalies.
Key Features
