An Early Warning System for Fires in Hospitals and Health Centers via the Internet of Things to Reduce Human and Material Losses

A fire alarm circuit is a basic circuit that, upon detecting fire, triggers an audible alert such as a buzzer or siren. In order to identify fires in a timely way and avoid any harm to persons or property, fire alarm circuits and smoke sensors are an integral aspect of security systems. Businesses, theatres, shopping centres, hospitals, and other public facilities must have fire alarms and smoke detectors installed by law. We designed a very simple fire alarm circuit out of everyday parts like the Arduino uno r3, the Flame sensor, the Wi-Fi module, the DHT11 temperature and humidity sensor, the Pressure sensor gy-68, the LCD screen, and the GSM module, in contrast to the many complex and expensive stand-alone devices available. This project aims to implement an IoT-based fire early warning system in healthcare facilities with the goal of reducing casualties and property damage.
