Gravity: Science Data Acquisition Module Kit for STEM Education

The Gravity: Science Data Acquisition Module Kit provides an accessible, no-code data logging system designed for STEM educators, students, and curious makers. It combines an intelligent data acquisition module, an onboard OLED display, and a suite of precision environmental sensors for immediate scientific exploration.

Plug-and-play scientific data logging

Designed for streamlined science investigations, this kit allows users to collect and analyse environmental readings without programming or manual data conversion. Sensors are automatically recognized and calibrated, displaying converted physical quantities directly on the screen.

Integrated DAQ module with OLED

The SCI DAQ module features a built-in 1.3-inch OLED screen, an RTC real-time clock, and 16MB of onboard storage for standalone data logging. It also outputs measured physical values over I2C, providing plug-and-play compatibility with micro:bit, Arduino, Raspberry Pi, and UNIHIKER boards.

Structured curriculum and experiments

Accompanied by dedicated educational tutorials, the kit covers biological, physical, and environmental science topics through a structured five-step scientific workflow. Learners gather, record, and analyse real-world data to draw evidence-based conclusions.

Four precision environmental sensors

The bundle includes an SHT31-F digital temperature and humidity sensor, an ENS160 air quality sensor measuring eCO2 and TVOC, a VEML7700 ambient light sensor capable of up to 120 klx, and an immersion gold analog soil moisture sensor.

Complete power and connection accessories

A 3xAA battery holder with a PH2.0-2P connector enables portable outdoor experiments, alongside a 2-in-1 Type-C and Micro USB cable for desktop power. The pack includes double-headed PH2.0 connection cables, an I2C/UART sensor cable, and a CR1220 coin cell battery.
