The Science Experiments Data Acquisition (DAQ) Module Kit is a versatile toolkit for conducting rapid digital scientific exploration experiments. Whether you are a STEM educator or a curious student interested in scientific exploration, you can utilize this toolkit to delve into various aspects of the surrounding environment, such as plant growth conditions and temperature and humidity data in smart homes.

Key Features:

• No programming required
• No need for scientific data conversion (data is available is the appropriate unit)
• No prerequisite knowledge of hardware electronics
• Plug-and-play functionality
• Easy data reading and analysis
• Automatic sensor identification
• Support 20+ popular sensors

At MCHobby we did discover the SCI DAQ and kindly appreciated the following features:

1. The two distincts I2C ports (with automatic sensor identification and data display)
2. The analog input (with possibility of selecting the attached sensor)
3. Retrieving the sensor data into a worksheet (connecting the module on a computer and the board expose itself as an USB drive)
4. Module can be a connected to an external microcontroler (via I2C) to make the calculated data available over the I2C bus.

About Science Data Acquisition (SCI DAQ) Module?

The Gravity: Science Data Acquisition (SCI DAQ) Module is a powerful and highly integrated data acquisition module that incorporates features such as screen display, automatic sensor recognition, sensor calibration, data logging, RTC clock, and data conversion to make data acquisition more convenient and efficient. In addition, the SCI DAQ module has versatile power options and can output physical quantity data collected by sensors through an I2C interface, compatible with micro:bit, Arduino, Raspberry Pi, UNIHIKER, etc.
