Tilt Sensor Module SW520D

🤔 What is a Tilt Sensor?A tilt sensor (also called a ball switch or mercury switch) is a digital switch that changes its output based on orientation. When tilted beyond a certain angle, the internal mechanism (metal ball or mercury drop) makes or breaks contact, changing the signal.📌 Key Features:Simple ON/OFF outputDetects if the object is upright or tiltedDigital signal (HIGH or LOW)No orientation angle info — only tilt or no tilt📦 Types of Tilt Sensors:TypeInside itBehaviorMetal ball typeRolling metal ballConducts when levelMercury typeLiquid metal dropConducts when tiltedMEMS Tilt...
