Smart Sensor Deals

Smart sensor deals for connected homes

Smart sensors for doors, windows, motion and water leaks are rounded up on this smart home page. Leak alarms under the sink and contact sensors on the back door send alerts straight to your phone, so a burst pipe or a forgotten open window gets noticed fast.

Which smart sensors does your home need?

• Match the sensor to the job, with contact sensors for doors and windows, motion sensors for rooms and leak sensors under sinks.
• Sensors connect either through a hub or directly over Wi-Fi, and hub-based ones usually run longer per battery.
• Battery type and expected life differ widely, so note whether it uses coin cells or AA batteries you already keep at home.
• Leak and temperature sensors only help if they notify your phone or sound a local siren, so confirm how warnings reach you.

Which suits you: Renters wanting simple peace of mind lean toward stick-on door and leak sensors, while homeowners building automations may add motion, temperature and humidity sensors throughout.
