PRODUCT DETAILS

Grove - 3-Axis Digital Accelerometer (LIS3DHTR) is a low-cost & power-saving 3 - Axis accelerometer in a bundle of Grove products. It is based on the LIS3DHTR chip which provides multiple ranges and interface selection. You can never believe that such a tiny 3 - Axis accelerometer can support I2C, SPI, and ADC GPIO interfaces, which means you can choose any way to connect with your development board. Besides, this accelerometer can also monitor the surrounding temperature to tune the error caused by it.

What are Accelerometers?

Accelerometers are electromechanical devices that measure acceleration, the rate of change in velocity of an object. It uses axis-based motion sensing, as a way of detection. In this blog, I’ll be recommending the ADXL335 and ADXL356C accelerometers with a quick assessment of each through my buying guide.
