This　article　introduces　a　new　digital　inclinometer.　It　is　designed　by　the　combination　of　MEMS　sensors　and　LPC1114　which　is　popular　with　low-power,　low-cost　32-bit　cortex-M0　embedded　microprocessor　on　the　market.　Kalman　fitter　the　Digital　signal　output　of　MEMS　accelerometer　and　gyroscope.　Then　calculate　the　inclination　angle　in　degrees.　Finally,　transfers　data　to　a　remote　server.　The　instrument　is　low　cost,　fast　signal　processing　speed,　and　solar　green　energy.　It　has　a　small　size,　light　weight,　high　accuracy　and　high　precision.　Then,　it　can　be　widely　used　in　the　tower　tilting　real-time　monitoring　of　electricity,　buildings,　bridges　and　gravity　reference　system.
