Overview

The Child Presence Detection System Market is gaining significant momentum globally, driven by growing awareness about child safety in vehicles and increasing government mandates to prevent hot car deaths. These systems are designed to detect the presence of a child left unattended inside a vehicle and alert caregivers or emergency services, thereby preventing life-threatening situations due to heatstroke or suffocation.

In 2024, the market was valued at approximately USD 220 million, and it is projected to grow at a CAGR of over 25% through 2030. Rapid advancements in sensor technologies, integration with vehicle ADAS (Advanced Driver Assistance Systems), and legislative push from regions like the European Union and the United States are fueling adoption.
