1 induction module power about one minute after the initialization time, at this time the module will output 0-3 times a minute, a minute into the standby state.
Free flow of wind, the wind will cause interference to the sensor.
Or from right to left through the infrared spectrum to reach the dual time, distance difference, the greater the difference, the more sensitive induction, when the body from the front to the probe
Head or from top to bottom or from bottom to top direction, the dual element can not detect infrared spectral distance changes, no difference, so the sensor insensitive or does not work; so the sensor should be installed so that the direction of the probe dual And the direction of human activity as much as possible parallel to ensure that the body has been through
Probe dual element induction. In order to increase the sensing angle range, this module uses a circular lens, also makes the probe four sides are sensitive, but the left and right sides are still
However, compared with the upper and lower direction of the two induction range, sensitivity, installation must still try to according to the above requirements.
