是温度变化造成变形,继而导致车库门的传感器没有瞄准:在车库门两边靠近地面附近,有两个传感器,其一是发射,另一个是接受,当二者没有瞄准的时候,因接受器不能接收到发射器来的信号(即使发射器有信号),就作出判断认为是门有阻挡(或者车子或者人或者杂物),因此给出开门的信号。3 t* h& t$ B6 Z P2 E

The sensors are located on each side of the garage door. You can manually adjust to make them align. + |6 c6 I* E" a1 u7 E1 n- u$ ?2 S0 d# M+ w: o) b" X4 }
