Frequently Asked Questions(1) Interference factors: Active non-living objects can cause false alarms, such as moving metal and liquid. The equipment needs to be planned at the installation angle to avoid the sensor electromagnetic wave directly scanning electric fans, pets close to the sensor, and shaking metal curtains. (2) Non-interference factors: The sensor's electromagnetic waves can penetrate human clothing, curtains, thin wood, and glass. The sensor's installation angle and scanning range need to be determined based on the application. (3) Semi-interference factors:The sensor determines the presence of a human body and is not suitable for facing the air conditioner directly.
