The project consists of transceivers. Transmitters contain sensors. These sensors detect air molecules, such as gas in the air, as well as fire and smoke. These devices transmit the readings via the Arduino to the receiver wirelessly via Wi-Fi. In order for the recipient to receive these readings and display them in the form of an alert by means of an application on the mobile phone in addition to the bell,

If the readings are high, it means that there is gas or fire in the place of the transmitters, thus the red LED will be triggered in addition to the alarm buzzer. If the readings are not high, the green will be on.

These devices are placed in important places such as warehouses, hospitals and banks because of their importance and the presence of these devices is very important, especially as they work on wireless communication between the transmitter and the receiver, as their range reaches 1000 meters in open places and decreases in closed places such as the presence of walls and others.
