Anyone knows how it works? Sabi ng officemate ko it works by detecting the heat of the engine. Parang duda ako doon. What I know is, if I stand underneath a green light, it does not turn red.
it does turn red. stand below it and spread out your arms more, you have to take up more space. may parang motion sensor ata e parang sa mga motion sensor doorbells sa mga mall stores na nag didingdong kapag pumasok ka hehe.
