External sensor module for cat water fountain Key benefits - Auto on/off based on pet presence: fountain activates when your cat approaches and automatically stops about 30 seconds after the cat leaves, protecting the pump, reducing noise, saving energy, and minimizing water evaporation. - Energy and wear savings: intermittent operation extends pump life and lowers daily energy use and water loss. - Simple compatibility: designed for USB-powered dog water dispensers; connects with existing fountains using only the interior sensor unit (adapter and fountain not included). - No extra power adapters required: sensor operates without a separate power adapter. What it does - Detects your pet within about 3 m (9.8 ft) with a 180-degree field of view; triggers fountain on approach and stops 30 seconds after the pet moves away. - Note: The PET MARKET SENSOR may require a warm-up time to function properly; timing can vary with delay settings. Specifications - Detection range: ~3 m; Induction angle: 180 degrees - Fixed stop time: 30 seconds (may vary slightly) - Sensor requires a warm-up time to operate properly, depending on delay - Dimensions: 45 x 45 x 30 mm (1.77 x 1.77 x 1.18 in) - USB cable length: 180 cm (70 inches) Use scenarios - Daily household fountain: automate water delivery as soon as your cat approaches, then pause after leaving to reduce noise and evaporation. - Multi-pet households: prevent continuous fountain operation when pets are not present, conserving water and energy. - Office or travel setups: compatible with existing USB dispensers to maintain fresh water flow only when a pet is nearby. Dimensions and compatibility notes - Sensor dimensions: 45 x 45 x 30 mm - USB cable: 180 cm - No adapter or fountain included; interior sensor module intended for use with USB-powered fountains.
