1 the induction module has an initialization time of about a minute after electrifying, and the module will output 0-3 times at intervals, and will be in standby mode after one minute.
2., we should try to avoid interference lens such as light source near the surface of the direct module, so as to avoid misleading the interference signal, and avoid using the environment as far as possible.
Free flow of wind and wind will also cause interference to sensors.
3. the dual module probe is used in the sensing module. The window of the probe is rectangular, and the dual element (A yuan B yuan) is located at both ends of the longer direction, when the human body moves from left to right.
From the right to the left, when the infrared spectrum reaches the dual time and distance, the greater the difference, the more sensitive the sensor is.
When the head or from up or down or down to the upper direction, the dual detection does not change the infrared spectrum distance, no difference, so the induction is insensitive or not working; so the sensor should be installed as parallel to the direction of the most human activity when the sensor is installed.
The probe is induced by two elements. In order to increase the induction angle range, the module uses a circular lens, which also makes the probe all sides, but the left and right sides still exist.
Compared with the upper and lower two directions, the induction range is large and the sensitivity is strong.
Received the parts in good condition, Good Packaging.
