Gravity: RP2040 Science Data Acquisition Module

SKU: DFR0999

Gravity: RP2040 Science Data Acquisition (SCI DAQ) Module by DFRobot simplifies sensor use. Traditional sensors output raw signals needing manual conversion/programming, but this module offers automatic recognition, calibration, data conversion, screen display, logging, RTC, and I2C output. It supports 20+ sensors (temp, humidity, etc.) and works with micro:bit, Arduino, Raspberry Pi, etc. Ideal for scientific exploration, teaching, IoT. Note: Install a button cell (positive to acrylic) for RTC accuracy.
