The Gravity 0–10V ADC Module is a high-precision dual-channel analogue-to-digital converter designed to interface industrial-grade 0–10V sensors with microcontrollers and Linux-based systems. Built on the Texas Instruments ADS1115, it delivers 15-bit resolution (0.375 mV per step) with ±2 mV accuracy across the full 0–10V input range.

The module bridges the voltage gap between high-output industrial sensors (pressure transducers, flow meters, wind speed sensors) and low-voltage controllers like Arduino and Raspberry Pi — no external signal conditioning required. Dual I²C and UART interfaces with the standard Gravity 4-pin connector make integration straightforward.
