Digital Tilt Sensor for Arduino 2.54 Spacing Automatic power failure battery switchThe digital tilt sensor has a simple function, if the sensor is not placed on a strictly flat surface, the little steel ball in the green tube will slip to one end of it, so it will output 0 or 1 digital signal. Actually, strong vibration can affect its output, but generally speaking, it's about 3 degrees to make it slip from one side to the other side. Then you could know that its tilt angle could not be adjusted. Specification: Tilt switch module
