High Quality HC-SR501 IR Pyroelectric Infrared PIR Sensor Motion Detector Module

Description: Descriptions: Product Features.1. Full-automatic sensing (when someone enters the sensing range, then input high level, people leave the sensing range, then automatically delay off the high level output low level);.2. Reserve photosensitive control position, can add photoresistor, daytime or strong light does not sense (5539 photoresistor with the use of);.3. Two triggering modes (L can not be repeated, H can be repeated, jumper selection, the default is H).4. With induction blocking time (default 3-4 seconds); induction module in each induction output (high level to low level), you can set up a blocking time immediately after the sensor does not receive any induction signal in this time period. This function can be achieved (sensing output time and blocking time) the two interval work, can be applied to the interval detection products at the same time this function can effectively inhibit the load switching process generated by a variety of interference.5. Wide operating voltage range (default DC5V).6. Micro-power consumption, quiescent current of 65 microamps, especially suitable for dry battery-powered electrical products.Note: A. Non-repeatable trigger mode: i.e., after sensing the output high level, the output will be automatically triggered from the high level to low level.B. Repeatable Trigger Mode: i.e., if there is human body activity in its sensing range, its output will keep high level all the time.

After the module is powered on, there is an initialisation time of about one minute, during which the module will output 0-3 times at intervals. This time the module will output 0-3 times at intervals, after one minute After one minute, the module will enter standby mode.2. Try to avoid lighting and other sources of interference close to the module surface lens, so as not to introduce interference. Lens on the surface of the module, so as to avoid the introduction of interference signals to produce false action. Use the environment to avoid the flow of wind, wind will also cause interference to the sensor. The wind will also cause interference to the sensor.3. The induction module adopts dual-element probe, the window of the probe is rectangular. The window of the probe is rectangular, and the dual elements (A element and B element) are located at the ends of the longer direction. When the human body from left to right or right to left, the infrared spectrum time and distance to the double element has a difference, the larger the difference, the more sensitive the sensing. The larger the difference, the more sensitive the sensor, when the human body from the front towards the probe or from the top to the bottom or from the bottom to the top direction. When the human body walks towards the probe from the front or from the top to the bottom or from the bottom to the top, the dual element cannot detect the change of the infrared spectrum distance. infrared spectral distance changes, no difference, so the induction is not Therefore, the sensor is not sensitive or does not work; so when installing the sensor should make the probe So when installing the sensor should make the direction of the probe and the direction of the most human activities parallel as far as possible. Therefore, when installing the sensor, the direction of the probe should be as parallel as possible to the direction of the most human activity, to ensure that the human body passes by the probe dual element is sensed. Precautions.First, the DC operating voltage must meet our requirements of the value, too high and too low will affect the performance of the module, and the power supply must be required to go through a good voltage regulator filter, such as computer USB power supply, mobile phone charger power supply, the older 9V laminated battery can not meet the module work requirements, it is recommended that the customer with a transformer power supply and after three-terminal regulator chip regulator and then through the 220UF and 0.1UF capacitor filtering power supply. The power supply is filtered by 220UF and 0.1UF capacitor.Second, debugging the human body as far away from the induction area, sometimes 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 sensed when the module has been caused by the output, as well as debugging the human body do not touch the circuit part will also affect the module work, the more scientific approach is to connect the output side of an LED or a multimeter, cover the module with a newspaper, the person left the room, and so on for 2 minutes after the look! Is the module still always have output?Third, the module is not connected to the load can work normally, connected to the load after the work of the disorder, one reason is because the power supply capacity is very small load is more power-consuming, the load caused by voltage fluctuations caused by the work of the module error, another reason is that the load is powered when the work of the interference, such as relays or solenoids and other inductive loads will produce a reverse electromotive force, the work of the 315M transmitter board will be electromagnetic radiation, etc. will affect the module. module. The solution is as follows: A. Add inductive filter to the power supply part.B. Adopt the method of using different voltages for the load and module, for example: use 24V working voltage for the load and 12V working voltage for the module, and isolate them with a three-terminal voltage regulator C: Use a higher-capacity power supply.Fourth, the human body sensor module can only work indoors and the working environment should be avoided sunlight, strong lights directly irradiated, if the working environment has a strong radio frequency interference, you can use shielding measures. If there is strong airflow interference, close the doors and windows or prevent convection. Sensing area as far as possible to avoid being directly in front of the heating appliances and objects as well as easy to be blown by the wind debris and clothing.v. The human body sensing module is recommended to be installed in a sealed box, otherwise there may always be an output signal.Sixth, if the human body sensing module is required to detect an angle of less than 90 degrees, you can use opaque adhesive paper to cover the lens or cut to reduce the lens to achieve.Seven, the human body sensing module using dual-element probe, the human body's hands and feet and head movement direction and sensing sensitivity has a close connection, and the characteristics of the infrared module decided not to accurately control the sensing distance.Eight, the module in the probe (PIR) can be welded on the other side of the circuit board, the probe can also be extended with a double-core shielded wire, the length should be within 20 cm as well.
