The reflector will be vibrated when the object is slipping,thus the output signal of the photoelectric sensor will be changed. 當物體有相對滑動(dòng)時(shí)會(huì )引起反射鏡面的振動(dòng)，由此引起光電傳感器的輸出信號發(fā)生變化。
When the pest crawls through the electro-optical sensor, it will produce a high level signals and begins to count the pulse signal, the count to the pest's number can be realized. 當蟲(chóng)子通過(guò)光電傳感器時(shí)，光電傳感器輸出高電平信號對脈沖信號進(jìn)行計數，就實(shí)現了對蟲(chóng)子數量的統計。
