Includes accelerometers designed to measure acceleration in one or two axes, typically used in applications requiring precise measurement of linear acceleration. These devices operate within specific voltage ranges and sensitivity levels, often packaged in CLCC or T/R configurations. Excludes amorphous silicon solar cells, photovoltaic cells, mass flow sensors, water meters, handheld digital thermometers, pressure sensors, transducers, photoelectric and industrial optical sensors, encoders, microphones, and proximity sensors.
