Overview
In response to the COVID-19 pandemic, ensuring that every individual entering a public space is scanned for elevated body temperature and wearing a mask is crucial. Current manual systems for temperature scanning have proven inefficient due to human error and inconsistency, especially in large crowds.
This IoT-based automatic entry system solves these problems by integrating contactless temperature checks and mask detection into an automated entry barrier. It ensures only individuals who pass both checks are allowed entry, providing an efficient solution for busy public spaces.
Key Features
- Contactless Temperature Scanning: Measures forehead temperature without physical contact.
- Mask Detection System: Scans for mask-wearing using a camera and image processing.
- Automated Entry System: Operates a motorized barrier to control entry based on health safety checks.
- Real-time IoT Monitoring: Sends data (temperature, mask detection) to a server for tracking and record-keeping.
How It Works
- Temperature & Mask Detection:
- The system uses a camera and temperature sensor connected to a Raspberry Pi.
- The camera checks for mask compliance, while the sensor takes a temperature reading from the forehead.
- Automated Entry:
- If the temperature is normal and the mask is detected, the system triggers a motor that opens the barrier.
- If the person has a high temperature or isn’t wearing a mask, the system flashes a red light and prevents entry, alerting authorities.
- IoT Connectivity:
- The system is connected via an ESP8266 WiFi module, transmitting health data in real-time to a server.
- Authorities can take action if needed based on these alerts.
Components
- Raspberry Pi: The brain of the system, processes data from sensors and controls the barrier.
- DC Motor & Flap Mechanism: Automatically opens or closes the entry point based on the system’s decision.
- Temperature Sensor: Reads forehead temperature.
- Camera: Scans for the presence of a face mask.
- ESP8266 WiFi Module: Enables IoT connectivity to transmit data.
- Red/Green Indicators: Visual signals to indicate entry permission or denial.
- Buzzer Siren: Audible alert for unauthorized entry attempts.
Applications
- Public Transport Hubs: Railways and airports.
- Offices and Workspaces: For employee health safety.
- Museums & Amusement Parks: To ensure visitor compliance.
- Public Venues: Stadiums, malls, and other high-traffic areas.
Advantages
- Fully Automated: No human intervention is required, minimizing errors and inconsistency.
- Real-time Alerts: Health data is transmitted in real-time for immediate action.
Disadvantages
- Power Dependency: Requires a continuous power supply.
- Fixed Setup: Must be mounted securely to the ground.
