DFRobot (DFR0028) Sensor Module, Gravity Digital Tilt

DFR0028 is a digital tilt sensor for Arduino / Raspberry Pi. It is used todetect orientation. Inside the sensor, there is a ball that make contact withthe pins when the case is upright. Tilt the sensor over and the balls don'ttouch, thus not making a connection.Specifications:- Accessory Type: Digital Tilt Sensor Module- For Use With: Arduino / Raspberry Pi Board- Wide voltage range from 3.3V to 5V- Standard assembling struct (two 3mm holes with multiple of 5cm as interval)- Easily recognitive interfaces of sensors ("A" for analogue and "D" fordigital)- High quality connector- Immersion gold surface- Size: 22 x 30mm (0.87 x 1.18in)
