KX116-1064
Tri-Axis, User Selectable ± 2g, 4g, 8g, Digital (I²C/SPI) Output, Integrated Pedometer, FIFO/FILO buffer, 2x2x0.6mm LGA - KX116-1064

The KX116-1064 is a tri-axis ±2g, ±4g or ±8g silicon micromachined accelerometer with integrated Pedometer, 2048-byte buffer, orientation, Tap/Double-TapTM, activity detecting, and Free fall algorithms. The sense element is fabricated using Kionix’s proprietary plasma micromachining process technology. Acceleration sensing is based on the principle of a differential capacitance arising from acceleration-induced motion of the sense element, which further utilizes common mode cancellation to decrease errors from process variation, temperature, and environmental stress. The sense element is hermetically sealed at the wafer level by bonding a second silicon lid wafer to the device using a glass frit. A separate ASIC device packaged with the sense element provides signal conditioning, and intelligent user-programmable application algorithms. The accelerometer is delivered in a 2 x 2 x 0.6 mm LGA plastic package operating from a 1.71V – 3.6V DC supply. Voltage regulators are used to maintain constant internal operating voltages over the range of input supply voltages. This results in stable operating characteristics over the range of input supply voltages. I²C or SPI digital protocol is used to communicate with the chip to configure and check for updates to the orientation, Directional TapTM detection, Free fall detection, Pedometer and activity monitoring algorithms.

IoT Evaluation and Development Kit Cart Kionix's IoT evaluation kit utilizes hardware platform based on Nordic Semiconductor's Bluetooth LE SoC. The compact (27/32mm x 4.2mm), highly integrated modular sensor system integrates Kionix's accelerometer (KX122-1037), combo accel-mag (KMX62-1031), and combo accel-gyro (KXG07) sensors along with ROHM's barometric pressure sensor (BM1383AGLV). Additional sensors can be evaluated using the add-on board that can fit inside the kit. This enables measurement of 3D acceleration, 3D magnetism, 3D rotation, air pressure, and temperature, making it ideal for training, prototyping, and initial set development of IoT and wearable applications.
