Based on its QMEMS and semiconductor technologies, Seiko Epson Corp. has developed two new series of sensing platforms: the E Series, which consists of two multifunction sensor evaluation units, and the M Series, which are compact, specialized evaluation modules.
Epson's new sensing platforms combine hardware (a unit or module) that processes and digitizes sensor data and with software that displays and stores sensor data sent to a PC via one of the many wired, wireless and other interface options.
The multifunction sensor evaluation units in the E Series perform a variety of sensing tasks. They have a six-axis sensor, which consists of three Epson gyroscopes that provide high accuracy and stability (±1,000 deg/s) on three axes and a triaxial accelerometer with a dynamic range of ±6 G, a triaxial geomagnetic sensor, and a pressure sensor. These evaluation units are available with either a ZigBee or a USB interface for easy connection to a PC. They also come with an accessory board that can be used to freely expand the interfaces as well as a power source for use in an even wider range of evaluation environments.
The M Series consists of more compact and even easier-to-use sensor evaluation modules with specialized sensor functions. There are two models in the M Series: the S7U4E002002, a highly accurate motion sensor with six degrees of freedom, and the S7U4E002003, a position sensor with a GPS receiver. Specialized for a single function and sporting a compact design, each of these modules can easily be built into portable, hand-held evaluation equipment. A micro-USB interface board (sold separately) is also available for performing evaluations in a PC environment.
