Design and Fabrication of Heat Detection System in a Car Passenger Cabin

摘要

In this project we aim in placing a heat detection system in a car . The heat detection system would sense the rise in temperature inside the car. Because of increase in temperature during day time the requirement of cooling system in absence of person inside the car is a major concern. In order to meet this requirement a method to reduce the temperature inside a car is required .In our project we are using DHT-11 sensor to detect the heat change inside the car .This sensor which is connected by an Arduino uno board sends the signal to the motor which slides down the window and cools the interior . After attaining normal temperature the window again slides up. In the past few years many fatalities have been reported as the result of internal car heat. Problems arise when the temperature in a car cabin is too hot when parked under direct sunlight. The trapped and accumulated heat causes the temperature inside a car to reach temperatures soaring high temperatures..
