The microcapsule. In this project, we will build an IoT based fire detection project using an Infrared flame sensor, Smoke detector, temperature and humidity sensor and ESP32 with an email alert feature. Our fire detection project will be linked with the IFTTT web service to generate an email alert to notify users. Presented at the 3rd International Conference on Modern Technologies in Mechanical & Materials Engineering (MTME2025), Topi, Pakistan, 16–17 April 2025. Keywords 1 Internet of Things, fire safety, monitoring, microcontroller, ifttt, sensor. Introduction The increasing prevalence of fire incidents and their. Abstarct An extremely effective and cutting-edge technology that uses the Internet of Things to detect fires in real time and send out early alerts for prompt action is a smart fire detection system with early notifications.
