1. automatic: when someone enters the sensing range is input high level, people leaving the induction range is automatically delayed closing high level. Output low level.2. light control (optional): module to set aside a location, you can set the photo control, or strong light during the day without induction. Light control is an optional feature, factory photoresistance is not installed. If you want, please purchase the photoresistance installed.3. two trigger modes: l not repeatable, h can be repeated. Jumper option defaults to h.A. not repeatable trigger mode: after the sensor output high level, delay time is over, the output will automatically change from high to low level.B. can repeat triggered way: that induction output high level Hou, in delay time paragraph within, if has human in its induction range within activities, its output will has been maintained high level, until people left Hou only delay will high level becomes low level (induction module detection to human of each times activities Hou will automatically extended a delay time paragraph, and to finally once activities of time for delay time of starting points).4. induction blackout time (default setting: 0.2 sec): after each induction the induction module output (high level low level), you can immediately set a blackout time, during this time the sensor does not receive any sensor signal. This feature can be achieved (sensor output and blockade times) the interval between work, can be applied to interval detection products; at the same time this function can inhibit various disturbances load in the process of switching.5. wide operating voltage range: default voltage DC5V to 20V6. power consumption: quiescent current 65, particularly suitable for battery-powered appliances.7. high level signal output: can be easily docked with the circuit.1: power supply2: high and low level output3 power negativeH: repeatable triggersL: not repeatable triggersCDS: Photo controlInstructions for use:1. the induction module powers on for about one minute after initialization, this module can output interval during 0-3 time, one minute after entering standby.2. direct sunlight should be avoided as far as possible sources of interference, such as lighting close range module surface of the lens, so as not to introduce interference signals malfunction; using the environment as far as possible to avoid movement of the wind, the wind will cause interference to the sensor.3. induction module used double Yuan probe, probe of window for rectangular, double Yuan (a, Yuan b Yuan) is located in more long direction of ends, dang human from left to right or from right to left walked Shi, infrared spectrum reaches double Yuan of time, and distance has poor value, poor value more large, induction more sensitive, dang human from positive to probe or from Shang to Xia or from Xia to above to walked Shi, double Yuan detection does not to infrared spectrum distance of changes, no poor value, therefore induction does not sensitive or does not work ; So when the sensor is installed should probe the dual directions and the directions of human activities up to parallel as far as possible, ensure human passes has dual induction by probes. In order to increase the sensing angle, this module uses the circle lenses, also make probes sensors on all sides, but in both directions up and down left and right side is still strong induction range, sensitivity, must still be installed as far as possible according to the above requirements. HC-SR505HC-SR505 small body sensing module is based on infrared technology, automatic control products, high sensitivity, high reliability, ultra-small, ultra-low-voltage operation mode. Widely used in various auto-sensing of electrical equipment, especially battery-powered automatic control products.Technical parameters:Operating Voltage Range: DC4.5-20V

Automatic induction: to enter the sensing range of the output is high, people leave the sensor range automatically delay off high, output low. Ultra-small size.
Repeatable trigger: the sensor output high, the delay period, if there is human activity in its sensing range, the output will remain high until people leave after the high variable delay lOW (automatically extended sensor module detects the human body after every activity a delay period, and the last time an event is the starting point of the delay time).
Wide operating voltage range: the default operating voltage DC4.5V-20V.

4. Repeatable trigger mode: that is, after the induction output is high, in the delay period, if the body in its induction range of activities, the output will remain high until the delay after the person to become Low level.

Pyroelectric human body infrared sensor module, model: SR-602Sensing distance: up to 5 meters; recommended 0-3.5M.Output: high level, H=3.3V, L=0VPower supply DC: 3.3V-15VQuiescent current: 20uAFeatures and uses:This module has high sensitivity, fast response, small static power consumption, small size, easy to install, and is installed.The lens, the pin header has been soldered, and the power supply is provided without debugging. Can be used for body sensor lights, alarms, security, Access control on-demand imaging, automatic equipment for agriculture, forestry and mining.Key points:1. The high level time of the output of this product is adjustable, 2.5 seconds to 1 hour, the output time set at the factory.It is 2.5 seconds, and you can change one chip resistor if you need to change it. Please read the resistance value corresponding to the typical delay time.Refer to the relevant form below.2. Blocking time, 2 seconds, not adjustable.3. The factory is defined as repeatable trigger and cannot be changed.4. The supply voltage of this module is 3.3V to 15V, and the limit voltage is 2.8V to 18V.5. Module output timing is: output high level for 2 seconds after power-on, then go low, enter standbystatus. If the delay time is changed, the time when the module outputs a high level after power-on will increase accordingly, which can be understood asThe startup time after entering the normal working state after the electric power will increase.6. After installing the photosensitive element, it does not work during the day, work at night, does not contain photosensitive components, and works all day (There are no photodiodes on the module,please purchase separately if needed. Recommended: ordinary F3 photodiode)It is considered that there is no photosensitive element installed.7. This module is very sensitive, pay attention to the installation position, try to avoid the heat source radiation source (air outlet / direct sunlight)8. The sensitivity of this module is adjustable, and you need to change a chip resistor. Please read the relevant table below for details.grid.9. When soldering with 220V ordinary soldering iron, it is necessary to unplug the power supply before welding. It is recommended to use24V low voltage soldering iron, such as domestic white light 936.
