Welcome to our store! Wide Application: The human body infrared sensor module can be widely used in all kinds of automatic induction equipment, especially the automatic control products powered by dry batteries. Fully Automatic Induction: When a person enters the induction area, it emits a high level, and when a person leaves the induction area, the high level automatically turns off after a delay, and the output is low level. Multi : 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. Advantage: 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. Parameter: The output time is from 0.5S to 200S, the operating voltage range is DC 4.8-20V, and the quiescent current is less than 50uA. For the trigger mode, L cannot repeat trigger and H can repeat trigger (default repeat trigger). Specification: - Item Type: PIR Sensor Module - Material: PCB - Applications: Widely used in various types of automatic induction equipment - Operating Voltage Range: DC 4.8-20V - Quiescent Current: less than 50uA - Level Output: High 3.3V/Low 0V - Trigger Mode: L cannot repeat trigger and H can repeat trigger (Default repeat trigger) - Delay Time: 0.5-200s (adjustable) can be produced within the range of a few tenths of a second - tens of minutes - Blocking Time: 2.5s (standard) can be made within the range of tenths of a second - tens of seconds - Circuit Board Dimensions: Approx. 32x24 mm/1.26x0.94 inches - Sensing Angle: less than 100° cone angle - Working Temperature: -15-+70 ℃ - Sensing Lens Size: 23 mm/0.91 inches 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 standby mode after one minute. 2. Try to avoid light and other sources of interference directly shining on the lens on the module surface at close range to avoid introducing interference signals and causing errors. Also, try to avoid flowing wind in the use environment, as wind can also interfere with the sensor. 3. The induction module uses a dual-element probe, and the probe's window is rectangular. The dual elements (element A element B) are located at both ends of the longer direction. When the human body moves from left to right or from right to left, there is a difference in the time and distance of the infrared spectrum reaching the dual-element sensor. The greater the difference, the more sensitive the induction. When the human body moves from the front to the probe or from top to bottom or from bottom to top, the dual element cannot detect the change in 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 probe's dual element should be as parallel as possible to the direction of most human activity to ensure that the human body is successively sensed by the probe's dual element. To increase the sensing angle range, this module uses a circular lens, which also makes the probe sensible on all sides, but the left and right sides are still larger and more sensitive than the upper and lower directions.
