Infrared Human Sensor, Ceiling Mounted, RS485

This human body infrared sensor provides a 360° monitoring range and more efficient detection performance through a ceiling mounted installation. The sensor has a wide range of applications, precise detection, low false alarms, and is suitable for various working environments.

Features

• Infrared human sensor can work continuously 24 hours a day, providing users with continuous security protection.
• The human body infrared sensor uses high-precision technology, which can accurately identify human activities and maintain stable performance, and can run for a long time without trouble.
• Through the distribution software, users can flexibly choose the duration of the alarm, providing three optional modes of 30 seconds, 10 seconds and 5 seconds.
• When an intruder enters the detection area, the sensor can automatically identify and sense the human activities in the area and trigger the alarm in real time.
• Its shell is made of high-strength PVC environmentally friendly material, which is resistant to high temperature, combustion and pressure, ensuring long-term durability.
• The detector adopts a ceiling-mounted installation method to ensure no blind spots, cover a wider detection area, and is easy to install and does not take up space.

Applications

Tips: The working principle of ceiling-mounted infrared human sensor

• The working principle of the ceiling mounted infrared human body sensor is similar to that of ordinary passive infrared sensors, mainly through the following steps:
• Thermal radiation detection: The human body emits infrared radiation through its own temperature. When the human body enters the monitoring area of the sensor, the amount of infrared radiation will change.
• Infrared change recognition: The infrared detection element inside the sensor can sense the changes in infrared radiation.
• Signal processing and triggering: When the sensor detects sufficient changes in thermal radiation, it will transmit the signal to the control system, triggering the corresponding device action.
