The KAI-2010-12-40-A-EVK evaluation board and sensor assembly is an integrated device/system for testing and development purposes. Specifically, it is designed to perform environmental temperature sensing as well as linear and angular motion sensing. Its application field includes industrial, medical, consumer electronics and automotive sectors. This evaluation board and sensor assembly is based on the KAI-2010-12-40-A-EVK reference design from Kionix.

This evaluation board features a pair of Kionix’s KXG02-1340LS linear motion sensors and a pair of KXS08-1224LA-C angular motion sensors. It also has an 8-bit Digital-to-Analog Converter (DAC) and a 12-bit Data Acquisition System (DAQ). The KXG02 and the KXS08 are part of the Kionix KXG02/KXS08 bipolar-sensor family of motion sensors, which are capable of providing accurate three-axis motion information.

The board also has an onboard 12-bit ADC (Analog-to-Digital Converter) to convert digital motion signals to analog temperature information as an input to the DAC. This feature allows the on-board temperature sensor to sample the environment and monitor environmental temperature changes. The construction of the board also ensures minimal electromagnetic interference, as it is shielded with integrated circuitry, with an included sensor-shielding plate, to protect the sensitive output signal.

The KAI-2010-12-40-A-EVK evaluation board and sensor assembly allow users to quickly and easily evaluate and develop motion sensing systems. The integrated design reduces development time and cost, and provides high accuracy and precision motion sensing data. Furthermore, the on-board temperature sensor helps users ensure that their device is operating in optimal conditions.

The working principle behind the KAI-2010-12-40-A-EVK evaluation board and sensor assembly is based on the principle of sensing linear and angular motion as well as changes in temperature. The on-board ADC is responsible for converting the digital motion signals into analog temperature information. This information is then used by the DAC to adjust the output voltage according to the current environment temperature. The KXG02-1340LS and KXS08-1224LA-C sensors are used to detect linear and angular motion respectively.

These motion sensors are electrically-driven cantilever-type vibrating gyroscopes with a MEMS-based (Micro Electro-Mechanical System) construction. The angular motion is measured by capacitance changes between the cantilever actuators and the sense electrodes. The linear motion is measured by a combination of the tilt information with the capacitive actuation-feedback signals. The accelerations and other motions sensed by the KXG02/KXS08 sensors are converted to digital output, which are sent via I2C to the microcontroller. The microcontroller then processes the motion data and can be used to control other system elements like LED, motors, etc.

The KAI-2010-12-40-A-EVK evaluation board and sensor assembly provide an easy and reliable way of evaluating and developing motion sensing systems. The integrated design reduces cost and development time and provides accurate and precise motion sensing data. Furthermore, the on-board temperature sensor allows users to protect their device from damages caused by temperature fluctuations. The Kionix KXG02/KXS08 sensor family allows for accurate three-axis motion detection, providing an optimal solution for motion sensing applications across various industries.
