Buying Guide

Connectivity matters

Choose between local alarm-only sensors and Wi‑Fi/LoRa hubs depending on whether you need remote alerts or simple on-site notification

Sensor count and placement

Match the number of sensors to risk areas—basements, sump pumps, water heaters, and appliance drains—to avoid blind spots

Alarm volume and local alerts

Look for clear decibel ratings or stated '100 dB' alarms if loud local notification is important in noisy spaces

Power and battery life

Prefer battery-operated models with long-life cells or replaceable batteries for areas without power access; check if base/hub requires mains power

Integration and automation

If you use smart home platforms, pick Wi‑Fi or hub-based sensors that support your ecosystem for automated shutoff or notifications

Durability and mounting

Opt for compact, water-resistant sensors with simple mounting or tethered probes for appliance rims and uneven floors
