阅读理解短文
A 12-year-old girl from Miller Middle School in San Jose has won the top prize with $25,000 in
a science fair.Her invention is a new fire detection system that can faster detect the heat sources.
It's also cheaper and more reliable than smoke detectors.
In the summer of 2022,a restaurant behind Shanya's house was burned to the ground.Since
then,Shanya's mother became increasingly cautious about the stove in the kitchen.It wasn't that
the restaurant didn't have smoke detectors,but they require there is a significant amount of smoke
first,which can sometimes mean a fire has already started and gotten out of control.This incident
inspired her to create a fire detection system to help people suffer less loss from fires.
One day,Shanya discovered that thermal cameras can detect heat loss in homes during winter
months.She wondered if these cameras could also spot house fires more quickly than traditional
smoke detectors.Shanya connected an affordable thermal camera to a tiny computer.She pro-
grammed her system to differentiate between people-which were identified as warm moving objects
-and heat sources,such as a turned-on gas burner,which were identified as hot objects that re-
mained still.The system can send a text message when it detects a fire but no human presence for
a continuous 10-minute period.
2
Shanya conducted multiple trials at various times of day and with people entering the camera's
view from different directions.In the end,Shanya's system accurately detected human presence
98%of the time and heat sources 97%of the time.Shanya determined that the best place for the
detector would be on the wall above the stove but under the stove range-this allowed its sensors
to have clear access to the most likely locations where a fire might start in a kitchen.
After her victory,the 12-year-old has said she wants to refine the device by combining it with
a smartphone app.The app will allow users to quickly switch over to a camera after receiving a
text message so they can see if the alert is correct.
