Features:
1. automatic induction: when someone enters your induction range, enter the high level, people leave the sensor range is
automatically delayed out high. Low output.
2. photosensitive control (optional): the module reserved for location, can be adjusted for photosensitive control, strong light during the day or not induction. The photosensitive control is optional, the factory did not install the photosensitive resistor. If necessary, purchase a separate photosensitive resistor to install.
3. two shooting modes: l is not repeatable, h is repeatable. It can be selected jumper, the default is h.
A. Non-repeatable trigger mode: the high induction output, the delay time is long, the output will automatically change from high to low.
B. Repeated triggering mode: that is, after feeling the high output, in the delay time period, if the human body in its activity
detection range, its output will remain high until the delay after the person will leave the high changes from level to low level(The detection module automatically delays a delay time after each activity of the human body, and takes the time of the last activity as the starting point of the delay time).
4. induction blocking time (default setting: 3-4 seconds): after each detection output (high level goes low), the detection module can be followed by a blocking time, during which the device is not detected receive any sense signals. This function can be used to reach the interval between the detection output time and the blocking time. It can be applied to interval detection products.
At the same time, this function can effectively suppress all types of interference in the load switching process.
5. wide operating voltage range: the standard operating voltage dc5v to 20v
6. micro-power: quiescent current 65 microamperes, especially for dry battery electrical products.
7. high level signal output: can be easily with various types of circuits to achieve the fit.
Instructions for use:
1 power induction module about one minute after the start-up time, at this time the module will output 0-3 times per minute, one minute in the standby state.
2. light and other interference must be avoided by directly closing the surface of the lens module, so as not to introduce
interference with the signal to produce malfunction; using the environment as far as possible to avoid
Free flow of wind, the wind will cause interference to the sensor.
3. sensor module with double element probe, the probe window is rectangular, double element (one yuan b yuan) in the longest direction at both ends, when the body from left to right
Or from right to left across the infrared spectrum to achieve double time, distance difference, the greater the difference, the more sensitive induction, when the body in front of the probe
Head or top to bottom or bottom to top direction, the double element cannot detect changes in infrared spectral distance, no difference, so that the sensor insensitive or not Work; so the sensor should be installed so that the direction of the double probe and the direction of human activity as much as possible parallel to ensure that the body has been through
Dual probe element induction. In order to increase the detection angle range, this module uses a circular lens, it also makes the probe four sides are sensitive, but the left and right sides are still
However, compared to the upper and lower direction of induction range two, sensitivity, the installation must still try according to the requirements above.
Use should pay attention to the following points:
1. DC voltage must meet our requirements, too high and too low will affect the performance of the module, but it also requires the power supply to be a good regulating filter, such as USB computer power, phone charger power supply mobile, the old 9v stacked battery is unable to meet the module's work requirements. It is recommended that customers use the power transformer and the regulator through the three-terminal voltage regulator and then through the power supply. capacitor filter 220uf and 0.1uf.
2. although the human body is not in front of the module, but the human body of the module is too close to the module can also be caused by the sensor output, just as the human body debugging does not touch the part of the circuit will also affect the work of the module, A more scientific approach is the output of a led or a multimeter, the module covered with a newspaper, people leavethe room, then 2 minutes to see if the module was or has an output?
3. the module does not take the load to work properly, connected to the load after the chaos work, one reason is because the capacity of en
