The Gravity Science Data Acquisition Module Kit is a comprehensive toolkit for conducting digital scientific experiments without programming or electronics knowledge. Built around the DFRobot SCI DAQ module, it includes four sensors covering soil moisture, ambient light, temperature/humidity, and air quality — everything needed for hands-on STEM exploration.

The SCI DAQ module features automatic sensor recognition, a built-in 1.3-inch OLED display, data logging with 16 MB onboard storage, and an RTC clock. Simply plug in a sensor, and the module handles data conversion and display automatically. It also outputs data via I2C, making it compatible with micro:bit, Arduino, Raspberry Pi, and UNIHIKER.
