The Memsic 2125 is a low cost, dual-axis thermal accelerometer capable of measuring tilt, acceleration, rotation, and vibration with a range of ±3 g. For integration into existing applications, the Memsic 2125 is electrically compatible with other popular accelerometers.
Memsic (http://www.memsic.com) 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.
Features:
- Measure 0 to ±3 g on either axis
- 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 3.3 or 5V operation: less than 4 mA at 5 vdc
Sample Applications:
- 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
