Compact Waterproof Leak Detection Sensor

High-precision water leak sensor sized at approx. 5 x 5 x 1.7 cm (2 x 2 x 0.7 in), mass 32 g (1.1 oz). Robust housing blends UL94 V-0 ABS flame-retardant plastic with soft, non-marking silicone edging. Powered by a single CR2032 battery (150 mAh), factory installed and tested — delivers >12 months service life under realistic alert frequency (20/day). Operational range: -10°C to +55°C — validated for UK winter sheds and Mediterranean summer attics alike. Wireless interface: ZigBee 3.0, ensuring secure, mesh-network-resilient connectivity. Employs a calibrated two-point electrode system with fixed 0.5 mm water depth activation threshold — independently verified for repeatability and environmental stability. On detection, triggers both local 85 dB siren and instantaneous mobile alert via ZigBee hub. Entire top surface is sealed against full immersion, enabling safe use in chronically damp locations including under-floor heating manifolds or condensate trays. No installation expertise required: place flat on clean, dry surface — no adhesives, screws, or power cables — and confirm pairing in under 60 seconds. Ideal for proactive monitoring in rental kitchens, care home bathrooms, office server rooms, holiday let properties, or anywhere fast leak identification prevents insurance claims and tenant disputes.
