Because the diverse demand of different application setting and user is caused,the much denaturation that passes feeling requirement is. To satisfy this kind of changeful requirement, IMU of aggregate of MEMS parts of an apparatus (inertial measure unit) can adopt a few more the following politic:

1, versatility: IMU should have a variety of passing feeling function, wait like accelerometer, gyroscope, magnetometer, in order to satisfy the requirement of different application setting. These sensor can be united in wedlock each other, provide more overall data.

2, high accuracy and tall stability: IMU should have high accuracy and tall stability, in order to ensure accurate measure and dependability. Through raising OPA335AIDBVR the sensitivity of sensor is mixed reduce noise level, the measurement that can raise IMU precision.

3, can configure gender and but process designing sex: IMU should be had can be configured and programmable is characteristic, in order to satisfy the requirement of different user. The parameter such as algorithm of wave of rate of the working mode that choose and the user can configure sensor according to his applied demand, sampling, filter.

4, data processing ability: IMU is OK and compositive data processing is unit, in order to offer real time data processing and analytic function. Can reduce pair of exterior processor so depend on, the real time sex that improves a system and answer speed.

5, interface and communication ability: IMU should have a variety of interface and communication agreement, so that have data switch and communication with other equipment. Common interface and communication agreement include I2C, SPI, UART, CAN to wait, can choose appropriate interface according to specific requirement.

6, low power comsumption and small size: IMU should have the characteristic of low power comsumption and small size, in order to satisfy the requirement of mobile equipment and portable equipment. Through optimizing circuit design and the sensor that use low power comsumption, can reduce power comsumption, prolong battery life.

7, high reliability and durable sex: IMU should have high reliability and durable sex, in order to suit all sorts of complex with harsh working environment. Through using high grade material is mixed enclose a technology reliably, can raise the dependability of IMU and durable sex.

The place on put together is narrated, IMU of aggregate of MEMS parts of an apparatus can pass versatility, high accuracy and tall stability, can configure gender and can the means such as ability of process designing sex, data processing, interface and communication ability, low power comsumption and small size, high reliability and durable sex will answer. These strategy can make IMU has better adaptability and expansibility below different application setting.
