One-way Tilt Sensor(white)
2013 the latest one-way tilt sensor is a digital module based on the steel ball switch .steel ball rolling downwards because the gravity , make the switch open or close. Unlike mercoid switchs ,steel ball switchs have no disadvantages such as damage, oxidation, gas leakage ,short life, environmental pollution, unsafety. So you can achieve very interesting interactive works through a 3p connecting sensor line connecting it with sensor shield .
