Door magnetic sensor

Door magnetic sensors (also known as door magnetic switches, door, and window sensors, or magnetic switches) are standard safety devices to monitor doors and windows opening and closing status. The smart sensor consists of two parts: magnets and sensors. These two parts are installed on the door or window frame and the corresponding door leaf or window. When the door or window is closed, the magnet is close to the sensor, and the smart sensor is in a non-triggered state; when the door or window is open, the magnet is far away from the smart sensor, causing the sensor’s status to change and trigger an alarm or other action. They are widely used in home security systems, safety monitoring in commercial places, and industrial automation.

Home security: The smart sensor is essential to the home alarm system. Once an abnormal opening is detected, an alarm message is immediately sent to the user or the monitoring center.

WIFI infrared body sensor

WiFi infrared body sensor is an intelligent device that combines infrared sensing technology and WiFi communication function. It can detect the movement or presence of the human body and send information to remote servers, smart home systems, or other networked devices through the WiFi network.

1. Working principle

Infrared Sensing: The WiFi infrared body sensor uses passive infrared (PIR) sensors to detect infrared radiation emitted by the human body. When someone enters the sensor’s detection range due to the difference in body temperature from the surrounding environment, the PIR sensor can capture this temperature difference change, thereby triggering sensing.
WiFi communication: Once human activity is detected, the sensor will send data to the Internet through the built-in WiFi module, and users can receive this information through mobile applications, cloud services, or other devices connected to the local network.

2. Main functions

Motion detection is mainly used to detect human movement in designated areas and is widely used in home and commercial security monitoring.
Presence detection: In addition to detecting movement, some advanced models can also perceive static presence; that is, even if a person does not move significantly, their presence can be recognized.
Intrusion alarm: In security applications, the smart sensor can immediately alert users, enhancing security.

3. Application Scenarios

Smart Home: Used for automatic lighting control, HVAC, sound systems, etc., to improve living comfort and energy-saving effects.

Working environment: This is used for automated management of meeting rooms, offices, and other areas, such as automatically turning on the projector and adjusting the indoor temperature.
Industrial automation: In a factory environment, it monitors personnel’s entry and exit to ensure safe operation and prevent accidents.
Elderly care: Help care for the elderly or patients, monitor their activity status, detect abnormalities promptly, and take measures.

Smoke sensing sensor

Smoke sensors (smoke detectors) are safety devices specifically designed to detect smoke in the air and early detect fire hazards. Many countries and regions have laws requiring specific types of buildings to install smoke sensors. For example, smoke sensors are mandatory in public facilities such as residences, work buildings, schools, and hospitals to ensure public safety.

Early Fire Warning: The smart sensor can respond quickly and sound an alarm when smoke begins to form in the early stages of a fire. This provides valuable time for evacuation and reduces the threat of fire to human life.
Automatic alarm: When smoke is detected, the smoke sensor will trigger the built-in high-decibel alarm to remind people to take action. Some advanced models can also send signals to the fire department or other emergency services through the networked system to ensure timely rescue.
Support for intelligent security systems: Modern smart home systems usually integrate smoke sensors. These sensors can not only be linked with other security devices in the home (such as cameras, door locks, etc.) but also remotely notify users through mobile applications, allowing them to stay informed even when they are not at home.

Acoustic and visual alarm

A sound and light alarm is a safety device that combines two warning methods: sound and light. It sounds an alarm in emergencies or specific conditions to attract people’s attention and take corresponding actions. It usually consists of a controller, speaker, and light-emitting device. When the system detects an abnormal situation or receives a trigger signal, the controller activates the sound and light-emitting devices, producing high-decibel sound and intense light to alert people.

Sound alarm: High-volume sound is emitted through the built-in speaker, continuous beeping, sirens, etc., ensuring it can be heard even in noisy environments.

Light alarm: Use high-brightness LED lights or other light sources, flashing or continuously illuminating, to provide visual warnings. This is especially suitable for noisy environments or hearing-limited situations.

Fire safety: Installed in buildings as part of the fire alarm system, it can issue an alarm promptly in the early stages of a fire and guide personnel to evacuate.
Security systems protect places such as residences, shops, warehouses, etc., and property safety from illegal intrusion.
Industrial field: In factories, chemical enterprises, and other places, sound and light alarms can monitor toxic and harmful gas leaks, machine failures, and other situations to ensure worker safety.
Healthcare: In hospitals, nursing homes, and other medical institutions, audible and visual alarms can help healthcare workers respond quickly to emergency calls or changes in patient conditions.
Public transportation: In emergencies, sound and light alarms can guide passengers to evacuate in an orderly manner at transportation hubs such as subway stations, train stations, and airports.
Smart Home: Integrated into smart home systems, used for real-time monitoring and alarming in various scenarios such as access control, smoke sensing, and water leakage sensing.
