Fire Detector With Embedded Programming Brian Guillen Project Mentor(s): Lad Holden
Fire Detectors have been around for over a century. They are crucial for warning us in the presence of a fire. Many fire detectors either detect heat, smoke, or have infrared detection. However, most fire detectors still use century-old technology. The fire detector developed for this project has embedded programming for accurate detection and fast response. The fire detector has two primary sensors for fire detection, thermistor for heat detection, and an infrared sensor for smoke detection. These sensors are interfaced with a microcontroller, which acts as a central control unit. This makes for an accurate fire detector that is inexpensive. Both sensors were experimentally tested to have proper functionality. The microcontroller monitors the data received from both sensors, regulating the system to accurately detect the presence of a fire. When a temperature of 130 Degrees Fahrenheit is reached, the microcontroller activates an alarm system that consists of an LED and buzzer. The embedded program in the microcontroller is optimized to consume small amounts of power, while sampling sensor data every 4 seconds. Overall, the integration of sensing, real time processing, and low-power consumption results in an accurate, responsive, and cost-effective fire detector. Presentation Type: Poster Presentation (May 21, 9:30am–3:00pm) Keywords : Sensor, Program, Microcontroller SOURCE Form ID: 84 The RC Buggy aims to demonstrate the balance between torque and speed to successfully compete in a slalom, drag race, and baja course. This project is the culmination of the engineering curriculum at Central Washington University. The objective of the project was to design and manufacture the drivetrain and chassis of a buggy operated by a remote control to compete in RC Baja Competition. Chassis with bumpers and cover was fabricated to support and protect all components. The Drivetrain powered rear wheels through sets of gears harnessing the power of a motor and battery system. During fall Quarter requirements were defined, and analyses were conducted to ensure fulfillment of requirements. Winter quarter a manufacturing plan was solidified; a variety of methods were employed to create the finished product. Manual machining techniques were utilized with the lathe, drill press, mill, and band saw for steel parts. While 3D printing out of PLA and PETG was used for the majority of the parts. Various parts such as gears, motor, and batteries were purchased. Once the car was manufactured, testing of vehicle performance and individual components were completed during spring quarter. Testing proved vehicles met predefined requirements for design and performance. Deflections test performed met the point load requirement of 25 lbs for the chassis. Speed test reached the minimum requirement of 25 mph. Car was able to withstand a solid impact at 25 mph without damage to any components.
