How it works
When someone enters its sensing range, the high level is input, and when the person leaves the sensing range, the high level is automatically delayed off. The output low level module has two triggering methods, respectively L non-repeatable and H repeatable, which can be selected by jumper, the default is H. - Non-repeatable trigger mode: that is, after the induction output high level, the output will automatically change from high level to low level once the delay time is over - Repeatable trigger mode: After the induction output is high, if there is human activity in the induction range during the delay time period, the output will remain high until the person leaves and then the high level will be changed to low level (the induction module will automatically delay a time period after detecting each human activity, and the time of the last activity will be the starting point of the delay time. (The starting point of the time delay is the time of the last activity.
