Abstract: This project introduces a smart environmental monitoring and alert system built using IoT technology. The system uses a NodeMCU (ESP8266) microcontroller connected to three important sensors: the DHT11 for measuring temperature and humidity, a Flame Sensor for detecting fire, and an MQ6 Gas Sensor for identifying dangerous gases like LPG and propane.Data from these sensors is collected in real time and sent to the Blynk IoT platform, where it can be viewed on a mobile app. The system also includes a Telegram Bot API that sends immediate alerts to the user’s Telegram account when dangerous situations occur, such as high temperature, gas leaks, or fire detection. This ensures that users are informed quickly, even if they are not physically present near the sensors. The system is affordable, easy to expand, and suitable for home safety, industrial use, and remote monitoring.Using IoT platforms and instant messaging services, this system provides a practical method for smart alerts and real-time detection of environmental dangers
