Xiaomi Motion Sensor 2S FAQ

Question

Accepted Answer

OverviewQ1: What are the selling points of the Xiaomi Motion Sensor 2S?A: The selling points of the Xiaomi Motion Sensor 2S are listed below:1. A new high sensing sensitivity is added, which can identify small movements such as leaning over and waving, and report the human body status in the space more accurately and quickly, thereby triggering precise instructions.2. With a longer battery life of 3 years, long-lasting and stable monitoring will be provided.3. Upgraded light sensor, which can quantitatively monitor the ambient light value (within the range of 0 to 1000 lux), matches a richer lighting environment scene, and you can formulate preferred instructions according to your needs.Note:The battery life is calculated by the Gewu Laboratory based on the evaluation of working conditions.
