2023CAPSTONEPROJECT
OBJECTIVE
CreateasystemofLow-Cost,Low-PowerDevicesthatcan DetectandReporttheOccurrenceandLocationofaWildfire Eventfromthefield.
VALUEPROPOSITION
OnAverage,Wildfiresimpactover7.2MillionAcresannually, harmingcommunities,ecosystems,andlives.
OurDevicescanidentifyWildfiresbytheacousticsoundthey produce,ReportingtheeventandLocationtoFirst Responders,longbeforetraditionalmethods.
PASTWORK
PastTeamsprioritizedSamaraLeafPayloadandTesting
DesignedPCBboards forsignalFiltering, Radio,andGPS.
Perunitcostof$32 andBatterylifeof 24hrs.
OURGOALS
ReduceUnitSizeandCost.
EstimateandVisualizeWildfirelocation.
ExtendtheworkinglifeofDevice.
CreateMeshNetwork.
