1.【How to use】： PIR Body infrared sensor module, PIR motion sensors have the jumper breakout for dual-mode operation . Works with any SOC, MCU or can even work stand-alone to build quick-n-dirty motion-activated lights, cameras or w/e. 2.【Quality】：This PIR motion sensor is more energy saving and environmental friendly human detector module with high quality, effective and low heating, long service life. 3.【Running smoothly】：These are adjustable motion sensors, which have small helpful potentiometers/pots on board to adjust on-time and sensitivity.They work well and do not need a library to run. 4.【Fully automatic induction】：When someone enters its sensing range, input high level, and when someone leaves the sensing range, it will automatically delay and turn off high level. Output low level. 5.【With induction blocking time (default setting: 3-4 seconds)】：after each induction output (high level to low level), the induction module can set a blocking time immediately, and sense in this time period The device does not receive any induction signal. This function can realize (induction output time and block time) interval work between the two, and can be applied to interval detection products; at the same time, this function can effectively suppress various interferences generated during load switching. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
