BR858017 36.12
The Memsic 2125 is a low cost, dual-axis thermal accelerometer capable of measuring dynamic acceleration (vibration) and static acceleration (gravity) with a range of 2 g. For integration into existing applications, the Memsic 2125 is electrically compatible with other popular accelerometers.

Some of the Memsic 2125's features:
  • Measure 0 to 2 g on either axis; less than 1 mg resolution
  • Fully temperature compensated over 0 to 70 C range
  • Simple, pulse output of g-force for X and Y axis
  • Analog output of temperature (TOut pin)
  • Low current operation: less than 4 mA at 5 vdc
A sampling of possible BASIC Stamp applications with the Memsic 2125 include:
  • Dual-axis tilt sensing for autonomous robotics applications
  • Single-axis rotational position sensing
  • Movement/Lack-of-movement sensing for alarm systems
  • R/C hobby projects such as autopilots
Memsic provides the 2125 in a surface-mount format. Parallax mounts the circuit on a through-hole providing all I/O connections so it can easily be inserted on a breadboard or through-hole prototype area.
