Product Description This product is retiring; quantity limited to stock on hand. LIS3DH 3-Axis Accelerometer Overview: The LIS3DH is a high performance, ultra-low power, three-axis linear accelerometer. It features user-selectable scales up to 16g, an embedded temperature sensor, 10-bit ADC and a standard digital I2C/SPI serial interface. Parallax Inc. places the LIS3DH on a compact 20×21 mm PCB with an 8-pin straight header. The I/O connections operate at the same voltage supplied to the VIN pin for compatibility with both 3.3 V and 5 V microcontrollers. The Parallax module includes a low-noise 2.5 V regulator which matches the LIS3DH factory calibration voltage for the highest possible accuracy. This LS3DH module is supported by the latest Propeller C libraries as well as dedicated BlocklyProp Solo blocks for easy visual programming. LIS3DH 3-Axis Accelerometer Features: Factory calibrated with 2.5 V low-noise regulator User-selectable full scales of 2 g, 4 g, 8 g, 16 g Hardware supports I2C, SPI 3-wire, & SPI 4-wire interfaces Over-voltage, reverse polarity, and signal contention protection of all signal pins VIN / GND reverse polarity protection Compatible with 3.3 V and 5 V microcontrollers Breadboard-friendly 8-pin header, plus 2 mounting holes Application Ideas: Motion activated functions Free-fall detection Intelligent power saving for handheld devices Gaming and virtual reality input devices Impact recognition and logging Vibration monitoring and compensation LIS3DH 3-Axis Accelerometer Key Specifications: Power requirements: 3 VDC to 5 VDC; maximum 1 mA Operating modes: High-resolution, normal mode or low-power Typical current consumption at VIN = 3.3 VDC, 50 Hz Output Data Rate (ODR): 761 µA Measurement ranges: ±2 g, ± 4 g, ±8 g, ±16 g Measurement sensitivity: 1 to 192 mg/digit, depending on selected mode Zero-g level offset accuracy: ±40mg Zero-g level change vs temperature: ±0.5° mg/C Temperature: range -40 to 85 °C; sensitivity 0.01%/°C, typical 8-bit resolution 1 digit/°C 32-level FIFO for each of the three output channels: X, Y, and Z Communication: I2C (100 or 400 kHz) or SPI (3 and 4 wire, up to 10 MHz) Operating temperature: -40 to 185 °F (-40 to 85 °C), Form factor: 8-pin male header with 0.1″ spacing PCB dimensions: 20 x 21 mm Mounting holes: Two holes suitable for #3 UNC (M2.5) hardware PCB assembled, tested, and completed in Rocklin, California
