The tilt sensor using MEC original tilt switch SW-460D, high sensitivity, the change is usually used to detect angle. Module without tilt or slope angle is not up to the preset threshold, DO port output high level, when the sensor tilt angle exceeds the preset threshold, module D0 output low level; Small digital output D0 can be directly connected with the MCU, the MCU to detect changes of level, thereby to detect objects angle; Small digital output DO can directly drive the relay module, which can form a tilt switch; Change of the sensor can sense the object angle Working voltage 3.3V-5V Digital output form output switch (0 and 1) A fixed bolt holes, easy to install Small PCB size: 3cm * 1.6cm
