MEMS technology based Tilt Sensor

Pyroelectro member Chris presents a very interesting project of building a working tilt sensor. The latest MEMS Technology based accelorometer sensor is used together with some digital circuitry and LEDs to build this Tilt Sensor. The Tilt sensor should have 3 core components:

  • A Custom Comparator Based Analog to Digtal Converter
  • An 8-State Machine To Drive The LED Matrix
  • Logic Buffers To Connect The A/D To The LED Matrix Display

 The 8-state machine uses a 555 timer, a 74-193 binary counter and a 74-238 de-multplexer.
