Product description: Grove - 3-axis digital I2C accelerometer ADXL357 - Seeedstudio 101020639
Digital3-axisaccelerometerof industrial quality, high accuracy and quality and low current consumption. It is based on the MEMS chipADXL357. It measures in three different ranges and accuracies:± 10 g at 51200 LSB/g, ± 20 g at 25600 LSB/g and ± 40 g at 12800 LSB/g.Minimal calibration is required to obtain accurate measurement results. The board is equipped withGroveconnector, which enables connection with main module usingI2Ccommunication, I2C address selection is possible.
Product is compatible with Arduino and Raspberry Pi.
