Acceleration displaces the proof mass, changing the differential capacitance between fixed and moving plates. A sigma-delta ADC converts the capacitance change to a 14-bit digital value. The embedded DSP engine processes the data for tap detection, tilt orientation, and activity monitoring without host processor intervention.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>VDD<\/td><td>Power supply (1.71-3.6V)<\/td><\/tr><tr><td>2<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>3<\/td><td>SDA\/SDI<\/td><td>I2C data \/ SPI MOSI<\/td><\/tr><tr><td>4<\/td><td>SCL\/SPC<\/td><td>I2C clock \/ SPI clock<\/td><\/tr><tr><td>5<\/td><td>SDO\/ADDR<\/td><td>SPI MISO \/ I2C address select<\/td><\/tr><tr><td>6<\/td><td>CS#<\/td><td>SPI chip select (low=SPI, high=I2C)<\/td><\/tr><tr><td>7<\/td><td>INT1<\/td><td>Interrupt 1 output<\/td><\/tr><tr><td>8<\/td><td>INT2<\/td><td>Interrupt 2 output<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Smartphone screen rotation<\/li><li>Wearable device motion tracking<\/li><li>IoT tilt\/orientation sensing<\/li><li>Industrial vibration monitoring<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Spec1<\/th><th>Spec2<\/th><\/tr><tr><td>LIS2DH12TR<\/td><td>STMicro<\/td><td>3-axis 14-bit<\/td><td>2x2mm<\/td><\/tr><tr><td>BMA456<\/td><td>Bosch<\/td><td>3-axis 16-bit<\/td><td>2x2mm<\/td><\/tr><tr><td>ADXL362BCCZ-RL7<\/td><td>ADI<\/td><td>3-axis 12-bit<\/td><td>3x3.25mm<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9727","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=9727"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9727\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9727"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9727"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9727"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9727"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
