7 Figure 2.1: The overall system of Carbon Monoxide Detection and Autonomous Countermeasure System for a mill use Wireless sensor and Actuator Network [4] Figure 2.1 show the overall system for the project[4]. The main system is the computer which is called as the base station. This is because, the computer will receive the signal from the sensor by TelosB, then send the command to the alarm system and internet server. Actuator will control siren and exhaust fan as the alarm system for the gas detector. In the final result, when the CO concentration crosses the threshold value
8 (which is 300ppm), the actuator circuit comes into action and the siren and exhaust fan are autonomously turned on through relay[]. Besides that, there is another related paper “Design, Characterization and Management of a wireless sensor Network for Smart Gas monitoring” by Faculty of Electrical Engineering and Computing, University of Zagreb, Croatia[5]. The system represent with energy management that involves three levels which are sensor level, node level and lastly network level. The sensor board is designed with a wireless sensor network (WSN) node that can autonomously send the recorded data by wireless [5]. The sensor board also contains with two modalities which are gas sensor and Pyroelectric Infrared (PIR) sensor. The network is multimodal that used information from the PIR sensor and neighbor nodes to detect the present of gas concentration and modulate the duty cycle of the node. Figure 2.2 below shows the design of the location of sensor placed in a different room. Figure 2.2: Design of the sensor location [5]
