GuardianBuddy aims to reduce child and pet deaths from overheating in hot cars through an affordable and effective product. It uses multiple sensors paired with an app to alert guardians of dangerous conditions in the car. Its innovative design is more effective than current options while still achieving a competitive price point, allowing it to potentially reduce preventable deaths by reaching a wider market. In the US, around 40 children die each year from being forgotten in hot cars, making GuardianBuddy's protection valuable.
