The use of Photodiode and Bluetooth Media in the Design of the Count of People who Enter the Room based on the ATmega8 Microcontroller

Smart Solutions to Regulate Room Density: ATMEGA8 Microcontroller-Based Microcontroller-Based Tools

In the current pandemic era, maintaining social distancing and limiting the number of people in a room have become crucial. To ensure compliance with health and security protocols, an effective system is needed to count people who enter and leave the room. One of the smart solutions is to use ATMEGA8 Microcontroller-based calculating tools, equipped with photodiode sensors. These tools are designed to automatically detect everyone who passes through the entrance of the room, providing an accurate and efficient way to monitor the number of people in the room.

The Role of Photodiode Sensors in People Counting

Photodiode sensors play a vital role in the detection process. When a person passes through the sensor area, the light received by the photodiode will change, this signal is then processed by the ATmega8 microcontroller. The microcontroller will process the data and record it as a "one person" in the total amount calculated. This information is then displayed on the LCD so that the room manager can monitor the number of people in the room in real-time.

Advantages of Using ATMEGA8 Microcontroller

The use of ATMEGA8 microcontroller-based tools offers several advantages, including:

*** Automatic and Accurate:** This system works automatically without requiring manual input, so it is more accurate and efficient. *** Real-time Monitoring:** The manager can monitor the number of people in the room in real-time, avoid overcrowding and support the health protocol. *** Easy to Install and Operate:** This tool is designed to be easily installed and operated, does not require special expertise. *** Safety and Efficiency:** This system helps maintain the safety of the room by ensuring that no one enters exceeding the maximum capacity, and increasing efficiency in managing the number of visitors.

Mechanism of Work

The mechanism of work of the ATMEGA8 microcontroller-based people counter is as follows:

Object Detection: Photodiode sensor captures changes in light that occurs when someone passes through the door.
Data Processing: ATmega8 microcontroller receives a signal from the sensor and processes the data, recording it as a "one person" in total.
Real-time Display: The calculation results are displayed on the LCD that provides real-time information about the number of people in the room.

Further Development

This person counter has the potential to be developed further with various additional features, such as:

*** Notification System:** Send notifications to the room manager when the number of people reaches a maximum limit. *** Integration of Bluetooth:** Allows data on the number of people in the room accessed remotely through a smartphone device. *** Record Data:** Record the number of people who enter and leave the room for visitor data analysis.

Integration of Bluetooth Media

The integration of Bluetooth media in the people counter system allows for remote access to the data on the number of people in the room. This feature enables the room manager to monitor the number of people in the room from a distance, using a smartphone device. This feature is particularly useful in large buildings or complexes where it is not possible to monitor the number of people in the room in real-time.

Conclusion

ATmega8 Microcontroller-based microcontroller calculation tool is a practical and effective solution for controlling the number of people in the room, maintaining security and compliance with health protocols. With easily accessible technology and relatively affordable costs, this tool can be applied in various places such as offices, schools, hospitals, and shopping centers. The use of photodiode sensors and Bluetooth media in the design of the people counter system provides an accurate and efficient way to monitor the number of people in the room, ensuring the safety and well-being of everyone in the room.
