FeaturesAutomatic induction: When someone enters its induction range, enter the high level, people leave the sensor range is automatically delayed off high Output low

 photosensitive control (optional): the module reserved for location, can be set to photosensitive control, strong light during the day or not induction. Photosensitive control is optional, the factory did not install photosensitive resistor. If necessary, please buy a separate photosensitive resistor to install

 Two trigger modes: L is not repeatable, H is repeatable. Can be jumper selected, the default is H
A: non-repeatable trigger mode: the induction output high, the delay time is over, the output will automatically change from high to low
B: Repeated trigger mode: that is, after sensing the output high, in the delay time period, if the human body in its sensing range of activities, its output will remain high until the delay after the person will leave the high The level changes to low level (the sensing module automatically delays a delay time after every activity of the human body, and takes the time of the last activity as the starting point of the delay time
 Induction blocking time (default setting: 3-4 seconds): After each sensing output (high level goes low), the sensing module can be followed by a blocking time, during which it is sensed The device does not receive any sense signals. This function can be used to achieve the interval between the sensing output time and the blocking time. It can be applied to the interval detection products. At the same time, this function can effectively suppress all kinds of interference in the process of load switching
Wide operating voltage range: the default operating voltage DC5V to 20V
 Micro-power: Quiescent current 65 microamps, especially for dry battery-powered electrical products
 Output high-level signal: can be easily with various types of circuits to achieve docking

:Instructions for use
 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 

 Light and other interference should be avoided Directly close the surface of the lens module, so as not to introduce interference with the signal to produce malfunction; use of the environment as far as possible to avoid
Free flow of wind, the wind will cause interference to the sensor

Sensor module with dual element probe, the probe window is rectangular, dual element (A yuan B yuan) in the longer direction at both ends, when the body from left to right
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

:Use should pay attention to the following points
the DC voltage must meet our requirements, too high and too low will affect the performance of the module, but also requires the power supply must be a good regulator filter, such as computer USB power, mobile phone charger power supply, the old 9V stacked battery Are unable to meet the module work requirements, it is recommended that customers use the power transformer and the regulator through the three-terminal voltage regulator and then through the 220UF and 0.1UF capacitor filter power supply.

Although the human body is not in front of the module, but the human body from the module is too close to the module can also be caused by the sensor output, as well as debugging the human body do not touch the circuit part will also affect the module work , A more scientific approach is to output a LED or a multimeter, the module covered with a newspaper, people leave the room, so 2 minutes to see whether the module has been or have output

the module does not take the load to work properly, connected to the load after the work of chaos, one reason is because the power capacity is very small load power consumption, load caused by voltage fluctuations caused by the module malfunction, the other reason is the load The power will have interference in the work, such as relays or electromagnets and other inductive load will produce a reverse electromotive force, 315M emission
