| # Fire Detection and Suppression System for Electric Ranges Team Members: - Arjun Swamy (arswamy2) - John Truong (jtruon9) - Prathamesh Salunke (salunke4) # Problem Electric ranges are responsible for 1,156 fires per million stoves in the US, which is 2.5x more than those caused by gas stoves. While smoke detection systems are able to alert authorities, they are often too late to prevent property damage and in some cases loss of life. The only way to stop this is to detect and suppress any unintended fires before it is allowed to spread. # Solution Our solution to this problem is a device that mount to the underside of the hood of the range. The device will use onboard sensors to determine if there is a fire and the approximate location of that fire. Using the location, a nozzle will align with the fire to spray a fire suppressant to control the fire that has already started. At the same time the device will send a signal to a kill-switch that will turn off power to the range, which will stop any more fires from forming. # Solution Components ## Fire Sensing Subsystem This subsystem will house the sensors and the PCB+microcontroller(ESP32-S3). The sensors that the MCU will get data from are an electrochemical CO2 level sensor(MG-811), a UV sensor(AS7331_T OLGA16 LF T&RDP) and an IR sensor(TPIS 1T 1084). The MCU will process the data from these sensors using our algorithm to determine whether or not to take action and if to take action, where the fire is located on the range. Power for this subsystem will come from the wall, likely where the hood is already plugged into. ## Fire Suppressant Release Subsystem This subsystem will be housed nearby the fire sensing subsystem and will be responsible for aiming the nozzle and releasing the stored fire suppressant. The aiming will be handled by controlling 2 servos(2183-2818-ND). The fire suppressant itself will be controlled using a solenoid valve(1528-1280-ND). This subsystem will also be powered from the wall. ## Kill-Switch Subsystem The kill switch subsystem will mainly be a relay(RC840T-240) that can handle the 240vac circuit that electric ranges are usually hooked up to. Additionally due to the distance between the hood and where the range is usually plugged into, this relay will need to be controlled wirelessly. A second MCU(ESP32-S3) that is wirelessly connected to the main MCU, can be used to accomplish the goal of this subsystem. # Criterion For Success For our project to be successful, the overall system will need to: 1. System accurately determines whether or not there is a fire within it's sensing area 2. Aim and release the fire suppressant at the sensed fire 3. Cut power to the range upon detection |
