We are looking for a customized 18.5-inch Full HD Android-based smart advertising screen for auto-rickshaws with 4GB RAM, 32GB storage, a SIM slot for 4G/5G connectivity, and a 12V DC power supply directly from the auto battery. The device must have a shockproof design to withstand vehicle vibrations and support cloud-based ad updates. Additionally, it should feature an external mmWave motion sensor (mounted on the roof) that detects passengers within 1.5 meters and triggers ads within 2 seconds; If no passengers are detected, the screen should enter sleep mode after 30 seconds. The screen should have a suitable port (USB/GPIO/UART) for sensor connectivity. Please confirm if you can manufacture this with complete customization, along with details on the estimated price per unit for bulk orders, MOQ, and lead time for manufacturing and delivery.
