Tuya PIR Motion Sensor Alarm

Tuya PIR Motion Sensor for Smart Life Wifi Based Alarm System

The Tuya PIR Motion Sensor seamlessly integrates with the Smart Life/Tuya ecosystem to add motion-based security and automation to your home. It uses passive infrared detection to monitor human/animal movement, sends real-time alerts to your phone, triggers smart scenes, and supports battery or USB power. With a 128° field of view, up to ~10 metres detection range and wide compatibility for smart home applications, it’s an ideal sensor for indoor smart alarm systems.

Features

Smart trigger: When motion is detected, the sensor sends a push notification through the Smart Life/Tuya app and can trigger other connected devices (lights, alarms, cameras).
Passive Infrared (PIR) detection: No emission of light or RF, detects based on body heat of people or animals passing by.
Wide-angle & long-range coverage: ~128° side view, ~128° downward view, detection distance up to ~10 m.
Low-battery alert: Built-in battery level monitoring sends you a notice in the app when battery is low, ensuring continuous protection.
Flexible installation: Mount via adhesive tape or screws for wall placement; takes LR-3/AAA batteries or USB power.
WiFi connectivity (2.4 GHz): Connects directly to your home WiFi network without needing a separate hub.
