With the development of society and the improvement of living standards, parents have more and more requirements for the function of baby carriages. In order to the environmental protection (air pollution weather, excessive light), security anti-theft (automatic brake, stealing alarm) and other functions, I did several researches about the current situation and solutions before designing and drawing the circuit diagram of the project, and finally completing the smart stroller with environmental protection and security anti-theft function. It can automatically purify the air inside the car in smog weather. Automatically sense the light intensity when the sun is too strong and open the awning to block the sunlight. It also has automatic brake and baby burglar alarm function.
