Description: An infrared motion detector alarm is designed to activate whenever a person enters its infrared detection zone. This sensor detects the movement of a human body, triggering an automatic alarm. The detection zone has a horizontal coverage of 80 degrees and a vertical range of up to 8 meters, with a vertical coverage angle of 20 degrees. A 30-second delay is implemented to allow individuals to exit the area before the alarm is triggered. The vertical coverage also enables positioning of the alarm to avoid activation by pets. The siren will sound for a few minutes before automatically turning off and resetting itself.
The infrared motion detector alarm operates using passive infrared (PIR) technology, which senses changes in infrared radiation emitted by objects in its field of view. The sensor consists of a pyroelectric element that detects the infrared radiation from a moving body, leading to a change in the output signal. When an object enters the detection zone, the sensor activates the alarm system.
The alarm system typically includes a microcontroller that processes the signals from the PIR sensor. The microcontroller is programmed to initiate the alarm sequence upon detecting movement. The 30-second delay feature is critical for user convenience, allowing individuals to move freely without triggering the alarm unintentionally.
The siren integrated into the system can vary in volume and tone, and it is designed to be loud enough to alert individuals nearby while potentially deterring intruders. After a predefined duration, usually a few minutes, the siren will deactivate automatically, and the system will reset, preparing for the next detection event.
To ensure optimal performance, the sensor's placement is crucial. The horizontal and vertical coverage angles must be considered to maximize detection while minimizing false alarms from pets or environmental factors. The system may also include additional features, such as adjustable sensitivity settings or the ability to connect to a home security network for remote monitoring.
Overall, the infrared motion detector alarm is an effective security measure that combines convenience with advanced technology to enhance safety in various environments.Do you know how infrared motion detector alarm Whenever someone comes in the infra-red zone. Infrared motion sensor, which detects moving human body. The alarm will sound automatically. The detection zone coverage is 80 degrees horizontally to 8 meters vertically and 20 degrees 30 second delay allows you to get out of the way before the alarm bel ls or system will activated. 20 degree vertical coverage allows you to the position alarm so pets will not be on the path alarm. A siren will sound for few minute, then turn off automatically and reset itself.
