En accelerometermodul som mäter statisk (gravitation) och dynamisk (vibration, "start och stopp") acceleration i x- och y-led. Sensorn mäter och presenterar även temperatur på en separat I/. kan enkelt anslutas direkt till BASIC Stamp, programexempel medföljer. Sensorn kan anslutas till i princip alla processorer, signalerna är av pulsvidds-typ.
Mycket användbar i tex robot och larmapplikationer.

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 module 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
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.
