Alarm system to detect the location of IOT-based public vehicle accidents

Traffic accidents are a thing that cannot be avoided by vehicle users. Many bus-related managers ignore vehicle engine maintenance from minor matters such as leaky fuel drains, supposedly replaceable vehicle brakes and short-circuit electrical connections. So in this study the author will make a fire detector and collision. The result of this tool will work when the MQ-135 sensor detects smoke, the fire sensor detects a fire and push button detects a collision. In addition to this tool also features GSM SIM800L module to provide information to the security agency. To facilitate the operation of the whole system is controlled by arduino uno microcontroller. After doing research MQ-135 sensor detects smoke when smoke comes into contact with the sensor, in addition to MQ-135 sensor in fire detection system used fire sensor module DFR0076, this module can detect fire up to distance 16 cm. While in the accident detection system (collision) is used push button. This tool system can be concluded that the overall design of the accident detection and fire detection equipment works well and the program used successfully applied to the system tool in accordance with the idea of design.
