VTI Technologies, a developer and producer of sensors that can sense angular motion, inclination and acceleration, has released the small 3-axis gyro sensor called CMR3000.
The sensor employs a common sensing mass and a multi-mode operational attached resonator with an orthogonal shape. These features eradicate cross talk between axes and need only a single drive loop. The patented basic phase-shift readout electronics that uses less power and wafer level quadrature signal design offers superior constancy in real life situations.

The CMR3000 uses less current of 5mA and in applications involving duty cycle, further 10% of current can be saved. This power save feature increases the lifespan of the battery twofold in moveable equipments such as a remote controller.
The product manager of VTI, Pekka Kostiainen, said that the market for the products using 3-axis gyro is thriving. The tiny size, superior constancy in sensitivity and lowest current use features would assist the company¡¦s clients to bring more products into the market, he added.
The CMR3000 is enhanced for applications including gaming and interface. The sensor has a calibration range of „b2000 dps with user-selectable calibration bandwidths to meet the needs of gaming applications. Its smallest volume of 3.1x4.2x0.8 mm with I2C and SPI interfaces allow it to be used in cell phones.
VTI has produced only samples to limited customers since 2010 summer. The mass production will commence in Q1 2011. One of the clients of VTI is producing a wireless targeting equipment using the CMR3000 and a cheap 8051 microcontroller.
