2. Try to avoid light and other interference sources that directly illuminate the lens on the surface of the module at close range, so as to avoid introducing interference signals and cause malfunctions; try to avoid flowing wind in the use environment, and wind will also cause interference to the sensor.
3. The induction module adopts dual element probe, the window of the probe is rectangular, the dual element (A element B element) is located at both ends of the longer direction, when the human body walks from left to right or from right to left, the infrared spectrum reaches the dual element There is a difference between the time and distance of the sensor. The larger the difference, the more sensitive the induction. When the human body walks from the front to the probe or from the top to the bottom or from the bottom to the top, the dual element cannot detect the change of the infrared spectral distance. There is no difference. Therefore, the induction is not sensitive or does not work; therefore, when installing the sensor, the direction of the dual element of the probe should be as parallel as possible to the direction of the most human activity, so as to ensure that the human body is successively sensed by the dual element of the probe. In order to increase the sensing angle range, this module uses a circular lens, which also makes the probe sense on all sides, but the left and right sides are still larger and more sensitive than the upper and lower directions.
