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.\n\nThe 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.\n\nKey Features\n\n\nNo Programming Required – Plug-and-play sensor reading and data logging\n\nAutomatic Sensor Recognition – SCI DAQ module detects connected sensors automatically\n\n1.3-Inch OLED Display – Real-time data readout on the module\n\n16 MB Onboard Storage – Log experimental data for later analysis\n\nRTC Clock – Timestamp data with included CR1220 battery\n\nSensor Calibration – Built-in calibration functions\n\nI2C Output – Compatible with micro:bit, Arduino, Raspberry Pi, UNIHIKER\n\nFlexible Power – 3.3–5.5V DC via USB or 3×AA battery holder\n\n\nIncluded Sensors\n\n\nAnalogue Soil Moisture Sensor – 3.3–5V, 0–4.2V output, 60×20×5 mm\n\nVEML7700 Ambient Light Sensor – I2C, 0–120 klx range, 0.0036 lx resolution\n\nSHT31-F Temperature & Humidity Sensor – I2C, ±0.2°C / ±2% RH accuracy, −40°C to 125°C range\n\nENS160 Air Quality Sensor – I2C, eCO2 (400–65,000 ppm) and TVOC (0–65,000 ppb)\n\n\nSCI DAQ Module Specifications\n\n\nOperating Voltage – 3.3–5.5V DC\n\nOperating Current – 40 mA\n\nInterfaces – 1× Digital/Analogue, 2× I2C/UART\n\nOutput – I2C (address 0x21–0x23)\n\nDisplay – 1.3-inch OLED\n\nStorage – 16 MB\n\nDimensions – 62 × 52 × 13 mm\n\n\nIdeal For\n\nSTEM education and classroom experiments\nEnvironmental monitoring: soil, light, temperature, humidity, air quality\nScience fair projects and student research\nIntroducing data acquisition without coding\n\n\nPackage Contents\n\n1× Gravity SCI DAQ Module\n1× Analogue Soil Moisture Sensor\n1× VEML7700 Ambient Light Sensor\n1× SHT31-F Temperature & Humidity Sensor\n1× ENS160 Air Quality Sensor\n1× 3×AA Battery Holder (PH2.0-2P)\n1× Type-C & Micro 2-in-1 USB Cable (1 m)\n1× RTC Battery (CR1220)\n4× Double-headed PH2.0-4P Cables (20 cm)\n2× Double-headed PH2.0-3P Cables (20 cm)\n1× Gravity 4P I2C/UART Sensor Cable (30 cm)\n\n\nResources\n\nScience Experiments Tutorials\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1473,"title":"Default Title","sku":"DF-EDU0170","price":143.23,"on_sale":false,"in_stock":true,"available_quantity":20,"option1":"Default Title"}]}
