My project is titled as Rescue and protection for coalminers using Arduino and wireless technology. The main objective to take up this project is to save lives of miners by detecting abnormal environmental conditions underground and take necessary steps to save their lives. In my project, I have used three different kind of sensors which are as follows;
[url removed, login to view] and Humidity sensor
[url removed, login to view] sensor
[url removed, login to view] sensor.
These three sensors senses temperature,humidity,inert gases and earthquakes beneath the [url removed, login to view],these sensors crosses the threshold level a buzzer at control room will be ON indicating that miners are in danger underground. This process is done wirelessly using zigbee technology so that data will be sent accurately within very less time.
