Product Overview This product is designed to enable the automatic windshield wiper and automatic headlight functions of vehicles. It optionally supports the automatic adjustment functions of air conditioning and HUD (Head-Up Display), providing multi-modal sensing support for driving safety and vehicle intelligence. Product Features Independently developed, exclusive fully localized solution with automotive-grade design, offering high cost-effectiveness and reliable supply. High-integration design, supporting detection functions of rainfall, ambient light, temperature, sunlight (optional), HUD (optional), and humidity (optional). The core rainfall detection function adopts an infrared total reflection scheme, ensuring stability, reliability, low power consumption, and long service life. Rainfall detection software algorithm with independent intellectual property rights: Aiming at complex working conditions such as tunnels, tree shades, and strong light, the algorithm integrates threshold self-learning, differential detection, digital filtering, temperature drift compensation, and aging compensation. It ensures the product’s adaptability to different automotive glass types as well as detection accuracy throughout the entire life cycle and all working conditions, effectively preventing failure to wipe or false wiping. Supports self-diagnosis for faults: including photoelectric device faults, overvoltage power supply, and undervoltage power supply, ensuring the validity of detection data.
