ITEM NAME:1Pcs HC-SR602 Mini Infrared PIR Human Motion Sensor Detector Module New Hot Descriptio n Description: Operating parameters: Human body pyroelectric infrared sensor module, Model: SR-602 Response distance: up to 5 m; 0-3.5 m recommended Output: high level, H = 3.3 V, L = 0 V DC power supply: 3.3 V-15 V Quiescent current: 20uA Specifications: Key points: 1. high output time of this product is adjustable, from 2.5 seconds to 1 hour, the output time at the factory. It is 2.5 seconds and you can change one chip resistor if you need to change it. 2. blocking time, 2 seconds, is not adjustable. 3. A plant is defined as a repeatable trigger and cannot be changed. 4. The power supply voltage of this module is from 3.3 V to 15 V in, and the limiting voltage is from 2.8 V to 18 V. 5. Module output time: high output within 2 seconds after power on, then go low, enter standby mode status. 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 as startup time after entering the normal operating state after increasing the electrical power. 6. After installing the Photosensitive element, it does not work during the day, works at night, does not contain photosensitive components, and works all day (There are no photodiodes on the module, if necessary, purchase separately. Recommended: a regular F3 photodiode). It is believed that the photosensitive element is not installed. 7. This module is very sensitive, pay attention to the installation position, try to avoid the source of heat radiation (air outlet / direct sunlight) 8. The sensitivity of this module is adjustable, and you must change the chip resistor. 9. When soldering with a conventional 220 V soldering iron, it is necessary to disconnect the power source before welding. It is recommended to use 24 V low voltage soldering iron, such as 936 internal white light. 10. If you follow the MCU and connect the lamp. Adjustment time delay.1xMH-SR602 Mini Motion Sensor Detector Module. Human body pyroelectric infrared sensor module, Model: SR-602. A plant is defined as a repeatable trigger and cannot be changed. If you follow the MCU and connect the lamp.
