Can, it is to judge unmanned presence in the second preset time if not having master reference 10 to trigger within timing certain time.All
After wanting master reference 10 to trigger once, caused trigger sequence, the i.e. former head are left out of office as long as no people occurs
It is secondary afterwards, then judge that people exists all the time.This avoid single pyroelectric infrared sensor people in the prior art it is motionless caused by can not
Test problems.
As shown in table 1, the utility model is likely to occur under scene with traditional single pyroelectric infrared sensor various
Comparison sheet.In table 1 it is listed be it is various be likely to occur scene, there is one also to have more people.It can be seen that with the single red biography of thermoelectricity of tradition
Sensor is significantly lower than the red sensor of single thermoelectricity compared to 100 erroneous judgement of pyroelectric infrared sensor component described in the utility model.Such as
Fruit has more people to pass in and out office, although the utility model can not also detect the presence of people under certain specific condition,
Overall detection efficiencies are higher than traditional single pyroelectric infrared sensor.
Table 1
Note：1) judge in table 1 in row with background color part for erroneous judgement.
2) in table 1 numeral 0 represent be not triggered, it is non-zero numeral represent be triggered, numeral 1,2 represent trigger sequence,
Wherein, 1 first 2 rear.
