The Gravity SCI DAQ Module is a multi-functional data acquisition module with a built-in 1.3-inch OLED screen for real-time sensor readings. It supports over 20 common sensor types including temperature, humidity, and barometric pressure — with automatic sensor recognition and a standardised I2C data output, so you can read any supported sensor using the same code.

Built-in 16MB storage with an RTC clock lets you log timestamped data for later analysis. The module standardises output across all supported sensors, significantly reducing the complexity of sensor interfacing for Arduino, UNIHIKER, and other I2C-compatible controllers.
