DFRobot has provided users with hundreds of sensors of all kinds. However, many of them output raw electrical signals like current, voltage, etc., and to obtain data in standard units of physical quantities, users need to look for relevant information in the product datasheets and convert data by formulas or coding. Meanwhile, the data format varies with different sensors, so each sensor requires a specific control program to be written. These would raise the bar for using sensors. Therefore, DFRobot develops this Gravity: SCI DAQ module that allows users to get sensor data in a simpler way. The Gravity: 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 storage, 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.
Applications:
  1. Scientific exploration: Improve the efficiency and accuracy of scientific exploration
  2. Interdisciplinary teaching: Allow teachers and students to easily complete interdisciplinary teaching, enrich teaching content, and improve teaching quality
  3. Agriculture and environmental monitoring: Collaborate with various environmental sensors for use in agriculture, water quality monitoring, meteorological observation, and other fields
  4. IoT applications: Function as a data acquisition module for IoT devices to achieve remote data transmission and control.

Features:

  1. Screen Display: The SCI DAQ Module has a built-in screen that can display real-time sensor data, making it easier for users to observe.
  2. Plug-and-play: The SCI DAQ Module can automatically recognize the type of I2C sensor connected, eliminating the need for manual settings and improving ease of use.
  3. Support Sensor Calibration: The SCI DAQ module can perform sensor calibration on the board. Sensors such as PH and TDS that require calibration before use can be quickly calibrated on the SCI acquisition module, ensuring data accuracy and reliability.
  4. Data Storage: The SCI DAQ Module has 16M of onboard storage, capable of storing more than 400,000 pieces of data. The stored data can be exported to a computer via a Type-C interface, making it convenient for users to analyze and process data.
  5. RTC Clock: The SCI DAQ Module has a high-precision real-time clock (RTC) that can record the time stamp for each data acquisition. This helps users easily track data trends and quickly perform data analysis and processing.

Package Includes:

1 x Gravity: SCI DAQ Module

1 x Double-headed PH2.0-4P Cable 20cm

1 x Double-headed PH2.0-3P Cable 20cm

1 x Gravity-4P I2C/UART Sensor Cable

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
