Sensors act as the "sensory organs" of smart homes, enabling automated control, energy optimization, and security by monitoring the environment and user behavior in real time.
1. Environmental Monitoring and Regulation
Temperature and Humidity Sensors: Detect indoor temperature and humidity, automatically triggering air conditioners, humidifiers, or dehumidifiers to maintain a comfortable environment.
Light Sensors: Adjust light brightness or motorized curtains based on natural light intensity, optimizing lighting and saving energy.
Air Quality Sensors (PM2.5/CO₂/VOC): Automatically activate fresh air systems or air purifiers when air pollution is detected, improving respiratory health.
2. Safety and Security
Human Infrared/Presence Sensors: Enable "lights turn on when someone is present, lights turn off when someone leaves," and can also be used to trigger security systems in "away mode."
Door and Window Magnetic Sensors: Monitor the opening and closing status of doors and windows, sending alarms and triggering camera captures when doors or windows are abnormally opened.
Smoke/Gas Sensor: Detects fires or gas leaks, automatically shuts off valves, and issues audible and visual alarms to ensure safety of life and property.
Water Leak Sensor: Installed in areas prone to leaks, such as kitchens and bathrooms, it automatically shuts off the water inlet valve upon detecting water accumulation.
3. Behavior Recognition and Intelligent Interaction:
Sound Sensor: Recognizes specific sound effects such as baby crying and breaking glass, promptly notifying users or triggering security responses.
Pressure/Acceleration Sensor: Used in smart mattresses or sofas to monitor prolonged sitting, sleep quality, and even fall risk.
Gesture Sensor: Enables control of lights, sounds, and other devices via gestures, enhancing the contactless interaction experience.
4. Energy Saving and Automation Scenarios:
Presence + Lighting Combination Control: Turns on lights only when someone is present and in low light conditions, balancing convenience and low energy consumption.
Smart Irrigation System: Soil moisture sensors link with watering devices, supplying water on demand to avoid waste.
AI learning sensors: such as the Aqara FP310, support AI spatial background learning, which can distinguish subtle movements (such as reading and napping) and improve judgment accuracy.
