1.2 Sensor Tap Dual infrared sensing for convenient hygiene: This basin mixer uses two infrared sensors, including a front sensor and an additional side sensor. Water flows instantly when hands are detected and stops when hands are removed. A 3minute automatic shutoff limits continuous flow to conserve water. Battery powered (AA, not included): Operates without mains power. Water is supplied automatically when hands are within sensing range and stops when hands are removed, providing touchless operation. Twovalve ceramic core design with manual override: The faucet features a solenoid valve and a ceramic core for reliable performance. You can manually switch off the infrared sensor and operate the tap with the twist handle, which is useful when traveling or when batteries are not available. Safe, predictable operation: The faucet activates immediately on sensor detection, stops on removal, and auto shuts off after 3 minutes if needed to prevent waste. Practical use scenarios: Home bathroom or kitchen: Hands operation enhances hygiene and reduces splashes, with quick manual override if batteries run low. Hospitality settings (hotels, guest houses, offices): Reliable touchless control for guests and staff, with builtin water saving through the 3minute autooff. Travel, camping, or offgrid use: Batterypowered convenience with a manual override, allowing use when power options are limited.
