Item Type: PIR Sensor Module Material: PCB Uses: Widely used in various types of automatic induction electrical equipment Operating Voltage Range: DC 4.8-20V Quiescent Current: <50uA Level Output: High 3.3V/Low 0V Trigger Mode: L can not be repeated trigger and H can be repeated trigger(Default repeated trigger) Delay Time: 0.5-200s (adjustable) can be produced in the range of a few tenths of a second - dozens of minutes Blocking Time: 2.5s (default) can be made in the range of tenths of seconds - tens of seconds Circuit Board Dimensions: Approx. 32x24mm/1.26x0.94in Sensing Angle: <100 Cone Angle Working Temperature: -15-+70 Sensing Lens Size: 23mm/0.91in in diameter How to 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. Try to avoid light and other interference sources that directly illuminate the lens on the surface of the module at close range, so as to avoid introducing interference signals and cause malfunctions; try to avoid flowing wind in the use environment, and wind will also cause interference to the sensor. 3. The induction module adopts dual element probe, the window of the probe is rectangular, 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 of the sensor. The larger the difference, the more sensitive the induction. When the human body walks from the front to the probe or from the top to the bottom or from the bottom to the top, the dual element cannot detect the change of the infrared spectral distance. There is no difference. Therefore, the induction is not sensitive 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. In order to increase the sensing angle range, this module uses a circular lens, which also makes the probe sense on all sides, but the left and right sides are still larger and more sensitive than the upper and lower directions. Package List 1 x Module 1Wide Application: The human body infrared sensor module can be widely used in all kinds of automatic induction electrical equipment, especially the automatic control products powered by dry batteries. 2Fully Automatic Induction: When a person enters the induction range, it outputs a high level, and when a person leaves the induction range, the high level is automatically turned off after a delay, and the output is low level. 3Multi Purpose: PIR IR module can automatically and quickly turn on various devices such as incandescent lamps, fluorescent lamps, buzzers, automatic doors, electric fans, dryers and automatic washing machines. 4Advantage: The human body infrared sensor module is an automatic control product based on infrared technology. It has the characteristics of high sensitivity, strong reliability, ultra low power consumption, and ultra low voltage working mode. 5Parameter: Output timing is from 0.5S to 200S, operating voltage range is DC 4.820V, quiescent current is <50uA. For trigger mode, L can not be repeated trigger and H can be repeated trigger (Default repeated trigger).
