Human Breathing Presence Sensor
A human presence sensor is an intelligent device that accurately detects human movement, stillness and slight motion within its range, converting sensing signals into trigger commands. It upgrades from traditional "motion detection" to "presence sensing", and is widely used in smart homes, security and other fields as a key component of intelligent scenarios.
| Rated Working Voltage 5V DC |
| Operating Current ≤ 50 mA |
| Standby Power Consumption ≤ 0.1 W |
| Operating Temperature Range -10 ℃ to +60 ℃ |
Product Details
Working Principle
It captures human physiological signals or motion characteristics to get detection results, with three mainstream technologies:
(1) Passive Infrared (PIR) — Basic Type
It relies on human infrared radiation and pyroelectric effect, with low power consumption and cost, but only sensitive to moving humans and prone to interference.
(2) Microwave Radar (including Millimeter Wave Radar) — Advanced Type
It actively emits microwaves/millimeter waves, detects humans (including stationary ones) via reflected wave differences, with high accuracy, strong anti-interference and 24/7 operation, but higher cost and power consumption.
(3) Multi-source Fusion Type — High-end Type
It combines PIR, radar and AI algorithms to avoid interference, improve accuracy, suitable for high-demand scenarios.

Product Features
(1) Accurate Detection
Identifies various human states, solves "lights off when people are present", with low false/missed alarm rate.
(2) Strong Environmental Adaptability
Unaffected by light and temperature; radar-type can penetrate non-metallic materials.
(3) Low Power & Easy Deployment
Low power consumption, optional wired/wireless power, flexible installation for new and old scenarios.
(4) Intelligent Linkage
Supports multiple communication protocols, links with lights/air conditioners for automatic control.
(5) Safe & Cost-effective
Radiation-free, with diverse models to meet different budgets and needs.

Application Scenarios
(1) Smart Homes
Links with home devices to realize automatic on/off, balancing convenience and energy saving.
(2) Public Services
Used in offices, malls and libraries to control equipment and reduce operating costs.
(3) Security Monitoring
Detects human intrusion and triggers warnings to ensure safety.
(4) Medical & Health
Monitors the elderly/patients and triggers nursing warnings in nursing homes and hospitals.
(5) Other Scenarios
Applied in vehicle-mounted systems, intelligent terminals and industrial production.
In summary, human presence sensors are core intelligent devices, and will be further upgraded to empower more scenarios.
