During this period, the module will output 0-3 times at intervals and enter the standby state after one minute.2. Avoid direct interference sources such as light from the lens on the surface of the module at close range to avoid introducing interference signals and causing false operation; avoid flowing wind in the use environment as much as possible, as wind will also interfere with the sensor.3. The induction module uses a dual-element probe. The window of the probe is rectangular. The dual elements (A element and B element) are located at both ends of the longer direction. When the human body walks from left to right or from right to left,there is a difference in the time and distance of the infrared spectrum reaching the dual element. The larger the difference, the more sensitive the inductionWhen the human body walks from the front to the probe or from top to bottom or from bottom to top, the dual element cannot detect the change in the infrared spectrum distance, so the induction is insensitive or does not work; therefore, when installing the sensor, the direction of the probe dual element should be as parallel as possible to the direction of the most human activity, to ensure that the human body is sensed by the probe dual element one after another when passing byIn order to increase the sensing angle range, this module uses a circular lens, which also allows the probe to sense on all four sides. However, the left and right sides still have a larger sensing range and stronger sensitivity than the upper and lower directions.Notice：The above requirements must still be followed as much as possible during installationNote: Follow the above requirements as much as possible during installation
