Ledgebit WiFi Smoke Sensor – Battery Powered Smart Fire Alarm

The Ledgebit battery-powered smoke alarm gives you smart fire protection in any home or office. It connects to Wi‑Fi via the Tuya platform and sends instant alerts during smoke or fire detection.

This battery-powered smoke alarm uses a photoelectric sensor, which is known for early detection of smoldering fires. It sounds a loud 85 dB siren and sends an app notification at the first sign of smoke. You can also silence or reset the alarm via the app—no climbing or buttons needed.

Installation is simple: just mount it on the ceiling or wall using the included bracket. It runs on 2 AAA batteries, lasting up to 2–3 years depending on usage. You’ll get an app alert when battery power is low, so you’re never caught off guard.

You can pair this device with other smart products from our Smart Devices Collection or enhance it using switches and triggers from our Smart Sensors Collection.

Built with ABS+PC flame-retardant material, this sensor is designed to withstand everyday home environments. It performs reliably between 0°C and 40°C and handles up to 90% humidity.

In summary, the Ledgebit Battery‑Powered Smoke Alarm offers smart detection, app notifications, and voice integration—all in a wire-free, easy-to-install design.
