ماژول CJMCU-8223 یک شتاب سنج سه محوره متشکل از دو چیپ NRF51822 و چیپ LIS3DH است که می تواند میزان شتاب را در محدوده ±2g/±4g/±8g/±16g اندازه گیری کند و از طریق بلوتوث و پروتکل ارتباطی I2C/SPI تبادل داده انجام دهد.
امکان تشخیص حرکت و امکان اندازه گیری میزان دما و ارسال داده به صورت 16 بیتی از ویژگی این ماژول شتاب سنج سه محوره است.
Description:
nRF51822 supports Bluetooth low energy protocol stacks as well as 2.4GHz protocol stacks, including Gazell, both available free of charge. nRF51822 requires a single power supply and gives the user the option of using on chip linear regulators giving a supply range of 1.8-3.6V, a direct 1.8V mode and a on chip DCDC buck converter giving a supply range of 2.1-3.6V. The use of the DC-DC converter can be dynamically controlled during run time and enables nRF51822 to operate at radio peak currents below 10 mA @ 3V supply (TX @ 0 dBm & RX).
