I'm looking to develop a silicone key sensor designed specifically for parents who may accidentally leave their children in the car. The sensor needs to be durable and emit a sound alert to remind parents that a child is in the vehicle. It's essential for the device to have an appealing design featuring an image of a car seat along with the text "Baby on Board." This product aims to enhance child safety and provide peace of mind for parents in my country, where this issue is becoming increasingly common. In terms of functionality, the sensor should be easy to use and integrate seamlessly with existing key fob designs. I'd like to explore different options regarding size, sound intensity, and battery life. Additionally, I'd appreciate it if you could provide information on any minimum order quantities and lead times for production. If you have any suggestions or existing products that might fit this concept, please share!
