Motion, presence and liht sensor, surface mounted, microwave 5.8GHz, ZigBee TUYA

5.8GHz ZigBee Presence Sensor with Light Detection (MSA050 Z1)

Reliable 5.8GHz microwave radar sensor designed for accurate human presence and motion detection in indoor environments. The sensor detects both movement and micro-movements, making it ideal for smart lighting and energy-saving applications.

Radar-based technology ensures stable performance regardless of temperature, airflow, or lighting conditions, making it more reliable than traditional PIR sensors.

Equipped with a ZigBee module (Tuya ecosystem), it can be easily integrated into smart home systems via gateway (MQTT / Home Assistant).
