Abstract:

Nowadays every system is automated in order to face new challenges. In the present days Automated systems have less manual operations, flexibility, reliability and accuracy. Due to this demand every field prefers automated control systems. Especially in the field of electronics automated systems are giving good performance. The system also provides audible alerts using a buzzer. The project aims in designing a coal mine safety system which is capable of detecting CO gas, temperature, humidity, LPG gas leakage, air quality and also Obstacle Detection. It also alerts the respected authorities at the control station through wireless Zigbee technology. And also this system gives the auto alarm through Buzzer if the sensor data exceeds threshold value. Zigbee is a PAN technology based on the IEEE 802.15.4 standard. Unlike Bluetooth or wireless USB devices, Zigbee devices have the ability to form a mesh network between nodes. Meshing is a type of daisy chaining from one device to another. This technique allows the short range of an individual node to be expanded and multiplied, covering a much larger area.
