System Components
Explore the core modules that make up the Medisafe intelligent gas leakage detection system.
MQ-2 Gas Sensor
Used to detect gas leaks such as LPG, methane, and smoke.
The MQ-2 is a versatile gas sensor ideal for detecting flammable gases and smoke. It plays a vital role in identifying gas leaks early and triggering alerts to minimize risk in hospital environments.
Arduino Uno
The core microcontroller managing sensor inputs and system responses.
Arduino Uno is used to process data from the MQ-2 sensor, control the buzzer and communication with the server. It is the brain of the detection system, programmed to trigger real-time alerts.
Piezoelectric Buzzer
Provides audible alerts during gas leakage.
The buzzer acts as an immediate alert mechanism within the hospital premises. It is triggered by the Arduino after 5 seconds once a gas concentration threshold is exceeded.
ESP8266
ESP8266 used for real-time health data processing and Wi-Fi communication.
The ESP8266 module serves as a real-time wireless communication device within the hospital premises. Once the gas concentration surpasses a defined threshold, the Arduino signals the ESP8266 to transmit an alert over Wi-Fi, enabling prompt notification through mobile apps, web dashboards, or emails.
Power Supply Unit
Supplies regulated voltage to all electronic components.
The power supply ensures the Arduino and sensor modules receive consistent and safe voltage, protecting the system from electrical surges or drops.

Biomedical EngineeringFrequently Asked Questions
What is the purpose of this project?
The project aims to detect harmful gas leaks (like LPG or methane) in hospital environments using IoT technology and immediately alert personnel to prevent hazards such as fires or poisoning.
Why is this system important in hospitals?
Hospitals often use gases like oxygen, nitrous oxide, and anesthetic gases, which can be flammable or toxic. Leakage can cause explosions or health issues for patients and staff, so early detection is crucial.
What components are used in this system?
Typical components include an Arduino Uno or Nano, an MQ series gas sensor such as the MQ-2, MQ-6, or MQ-135, a Wi-Fi module like the ESP8266, a buzzer, an LCD display or serial monitor, a relay module, and a suitable power supply.
How does the gas sensor work?
MQ sensors detect gas concentrations in the air by measuring changes in resistance. The sensor outputs an analog voltage that corresponds to the gas level.
How does the system send alerts?
When gas levels exceed a threshold, the Arduino turns on the Fan, shows warnings on an LCD, and sends data to the cloud or a mobile app via the ESP8266 Wi-Fi module.
Will the system still work without internet?
Yes. Local alerts like buzzers and LEDs still work without internet, but remote notifications via the cloud or mobile apps will not be delivered until connectivity is restored.
Where should detectors be installed in a hospital?
Detectors should be placed near gas storage areas, operation theaters, ICUs, and areas with frequent gas use or connections to ensure early leak detection.
Can this system shut off gas automatically?
Yes. With the addition of a relay module, the system can be configured to cut off the gas supply automatically when a leak is detected.
Can the system be expanded with other sensors?
Yes, the system can include other sensors like temperature, flame, humidity, or smoke sensors to enhance overall safety and environmental monitoring.
How reliable is the gas leakage detection system?
The system is highly reliable when calibrated properly. Regular testing and maintenance are necessary to ensure continued accuracy and functionality.
