Features:
1. Fully automatic induction. When a person enters the sensing range, it outputs a high level, and when a person leaves the sensing range, it automatically delays the high level and outputs a low level.
2. Photosensitive control (optional, not set at the factory) can be set to photosensitive control, and it will not sense during the day or when the light is strong.
3. Temperature compensation (optional, not set at the factory). In summer, when the ambient temperature rises to 30~32°C, the detection distance becomes slightly shorter, and the temperature compensation can make a certain performance compensation.
4. Two trigger modes (selectable by jumper):
  1.  Non-repeatable trigger mode: that is, after the induction output is high, the output will automatically change from high to low as soon as the delay time period ends.
  2. Repeatable triggering method: that is, after the induction output is high, within the delay time period, if there is a human body moving in its induction range, the output will keep the high level until the person leaves. Level to low level (after the sensing module detects each movement of the human body, it will automatically extend a delay time period, and the time of the last movement is the starting point of the delay time).
5. With induction blocking time (default setting is 2.5S blocking time). After each sensing output of the sensing module (the low level becomes the high level), a blocking time period can be set immediately, during which the sensor does not accept any sensing signal. This function can realize the interval work of "induction output time" and "blocking time", and can be applied to interval detection products. At the same time, this function can effectively suppress all kinds of interference generated during the load switching process. (This time can be set at a few tenths of a second to several tens of seconds).
6. Wide working voltage range: default working voltage DC4.5V-20V.
7. Micro power consumption: quiescent current < 50 microamps, especially suitable for automatic control products powered by dry batteries.
8. Output low-level signal: It is convenient to connect with various circuits. Instructions for use:
1. After the induction module is powered on, there is an initialization time of about one minute. During this period, the module will output 0-3 times at intervals, and enter the standby state after one minute.
2. It should be avoided as far as possible to avoid interference sources such as lights and other sources of direct exposure to the lens on the surface of the module, so as to avoid introducing interference signals and causing malfunctions. Try to avoid the flowing wind in the use environment, the wind will also cause interference to the sensor. 3. The induction module adopts a dual element probe, the window of the probe is rectangular, and the dual element (A element B element) is located at both ends of the longer direction. When the human body walks from left to right or from right to left, the infrared spectrum reaches the dual element. There is a difference between the time and distance, the greater the difference, the more sensitive the induction, when the human body walks from the front to the probe or from top to bottom or from bottom to top, the dual element cannot detect the change of infrared spectral distance, no difference value, so the sensing is insensitive or does not work. Therefore, when installing the sensor, the direction of the dual element of the probe should be as parallel as possible to the direction of the most human activity, so as to ensure that the human body is successively sensed by the dual element of the probe when passing by. In order to increase the sensing angle range, this module adopts a circular lens, which also makes the probe sense on all sides, but the left and right sides still have a larger sensing range and stronger sensitivity than the upper and lower directions. 4. Adjust the distance potentiometer to rotate clockwise, the sensing distance will increase (about 7 meters), otherwise, the sensing distance will decrease (about 3 meters).
5. Adjust the delay potentiometer to rotate clockwise, the induction delay will be longer (about 300S), otherwise, the induction delay will be shortened (about 0.5S).   HC-SR505 product description: HC-SR505 small human body induction module is an automatic control product based on infrared technology, with high sensitivity, strong reliability, small size and low voltage working mode. Widely used in all kinds of automatic induction electrical equipment, especially the automatic control products powered by dry batteries. Features:
1. Fully automatic induction: when a person enters the induction range, it outputs a high level, and when a person leaves the induction range, it automatically delays the high level and outputs a low level.
2. Small size.
3. Repeatable triggering method: that is, after the induction output is high, within the delay time period, if there is a human body moving in its induction range, the output will keep the high level until the person leaves. Level to low level (after the sensing module detects each activity of the human body, it will automatically extend a delay time period, and the time of the last activity is the starting point of the delay time).
4. Wide operating voltage range: the default operating voltage is DC4.5V-20V.
5. Micro power consumption: quiescent current < 50 microamps, especially suitable for automatic control products powered by dry batteries.
6. Output high-level signal: It can be easily connected with various circuits.

1. Fast response, low static power consumption, high sensitivity and small size.
2. Simple installation, the lens has been installed and the pin header has been welded, and the power supply is connected, no debugging is required. Feature Description:
1. The output high level time of this product is adjustable, from 2.5 seconds to 1 hour. The output time set at the factory is 2.5 seconds. If you need to change it, you can change a chip resistor.
2. The blocking time, 2 seconds, cannot be adjusted.
3. The factory definition is repeatable triggering 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. The output sequence of the module is: after power-on, it outputs a high level for 2 seconds, then becomes a low level and enters the standby state. If the delay time is changed, the time for the module to output a high level after power-on will increase accordingly, which can be understood as the start-up time of entering the normal working state after power-on will increase.
6. After the photosensitive element is installed, it will not work during the day, work at night, without the photosensitive element, and work all day (the default is that the photosensitive element is not installed).
7. This module is very sensitive, pay attention to the installation position and try to avoid the heat source radiation source (air outlet/direct sunlight).
8. The sensitivity of this module is adjustable, and a chip resistor needs to be changed.
9. When using a 200V ordinary soldering iron to solder, it is necessary to unplug the power supply before soldering. It is recommended to use a 24V low-voltage soldering iron.   RE200B Pyroelectric infrared sensor uses the characteristics of temperature change to detect infrared radiation, and uses the method of double sensitive elements to suppress the interference caused by temperature change, which improves the working stability of the sensor.
