Abstract [en]

WSN’s are more commonly used nowadays in both industry and research. Their main purpose generally involves some type of monitoring where they sense information from the environment, process the information, and take appropriate action (alarming, sending information further, displaying data, etc…). This thesis proposes a way to monitor leaks of volatile ethanol during transportation by integrating a sensor into an existing WSN. First, several sensors types are compared with each other to find the most suitable one based on cost, range, and power consumption. Once an appropriate sensor is selected, any necessary circuits are designed in EagleCad and printed using a PCB milling machine. After the PCB design, the circuit with the sensor is connected to a WSN which sends the information via GSM to a server running MYQSL database. A program is written which turns the sensor on periodically for enough time to warm up and retrieve data. Information is sent from the server to a GUI which displays the data on a PC console. An experiment is conducted which both simulates the environment in which the sensor could be placed and calibrates the sensor. After the experiment is done, three equations are extracted from the data which could be used to sense % ethanol in the air up to about 0.55%.
