Coal mine Safety and Alert System using IOT Electronics engineering final year project

Lm35 (Temperature) sensor reads Coal mine temperature. Heavy heat causes fires. Mq2 (CO) sensor reads CO emission in Coal mines. These sensors data will be displayed on LCD continuously. In abnormal condition gives buzzer sound to alert coal mine workers. WIFI (ESP8266/IOT) module sends sensor data to server continuously. User can see data in IOT server from anywhere. Before entering into coal mines workers has to observe data in IOT server and then leave.
