Presence sensor

Start by checking integration and power requirements that fit your installation. You’ll find WiFi Motion Sensor models compatible with apps and voice assistants, plus other PIR sensors like the 220–240 V AC ceiling sensor, which mounts on the ceiling and detects motion within a given range. Choose based on whether you want voice control via Alexa/Google Assistant, detection via direct Wi‑Fi, or a simple integration with your existing devices.

The WiFi Motion Sensor connects directly through Wi‑Fi and can be controlled remotely via an app, with voice support via Google Assistant and Amazon Alexa. This connected capability lets you check status and alerts wherever you are, without needing a central hub. In comparison, wall PIR models run on power and can offer 360° detection in a specific area, often without needing a third-party app.

They’re ideal for home security and for controlling lighting or connected devices. A WiFi sensor can send alerts and trigger actions through the app—useful for monitoring presence in a room or detecting door opening. A ceiling PIR sensor provides coverage up to 6 meters with 360° detection, making it a good fit for hallways or areas that need continuous monitoring.

Make sure your setup is compatible with the power type and the protocol of the chosen sensor. Some models work on 110–240 V and require a fixed installation, while others connect via Wi‑Fi without a hub. Also check compatibility with your voice assistants and your home network to ensure smooth integration.

They’re suitable for both residential protection and small offices or shops that need motion detection. Sensors with a voice assistant and direct Wi‑Fi make notifications and automations easier, while wall or ceiling PIR sensors meet simpler, more robust needs such as automatic lighting or presence alerts.

In the same family, you’ll find door/window opening sensors, EAS systems, and other security sensors—some offering instant notifications and bright light alarms. These options help you deploy a more complete smart home solution by combining detection, alerts, and lighting controls based on the areas being monitored.
