Tuya Smart PIR Motion Detector Sensor

This device is a WiFi-enabled Passive Infrared (PIR) Motion Sensor, designed for smart home security and automation within the Tuya and Smart Life ecosystems.
It detects human or animal movement by sensing infrared energy fluctuations in the environment.

Technical Specifications & Features

1. Sensor Technology: Uses a Fresnel lens to focus infrared radiation onto a pyroelectric sensor, allowing for wide-angle detection (typically around 110° to 120°).

2. Connectivity: Operates on the 2.4GHz WiFi band (IEEE 802.11b/g/n). It connects directly to your router without requiring a dedicated central hub.

3. Power Management: Typically powered by AAA batteries or a CR123A lithium battery, featuring ultra-low power consumption for long standby times.

4. Ecosystem Integration: * Apps: Fully compatible with Tuya Smart and Smart Life apps.

5. Voice Control: Supports integration with Amazon Alexa and Google Assistant for status queries and routine triggers.

6. Alert System: Provides real-time app push notifications to a smartphone whenever movement is detected.

Primary Use Cases

1. Security: Acts as a 24/7 monitor for unauthorized entry in homes, offices, or garages.

2. Automation (Scene Triggering): Can be linked to other smart devices. For example, it can automatically turn on smart lights when you enter a room or activate a smart siren if movement is detected while you are away.

3. Safety: Monitoring movement in the homes of elderly relatives to ensure they are active and safe.
Installation Note

The device is usually "plug-and-play," featuring a 360-degree adjustable base or adhesive mounting, allowing it to be placed on walls, ceilings, or flat surfaces.
